in the national AIDS behavioral surveys sample of 2673 adult heterosexual, .2% (thats .0002 as a decimal fraction) had both received a blood transfusion, and had a sexual partner from a group at high risk of AIDS. explain why we cant use the large-sample confidence interval to estimate the proportion p in the population who share these two risk factors. Solution Due to personal bias and non response bias, the results so obtained from the sample are more likely to be under estimates. Some respondents may underreport to the question whether they had a sexual partner from a group at high risk of AIDS because of embarrassment and fear or they may forgot or not know the details of their own or partners status of blood transfusion. Since the results are underestimates use of large-sample confidence interval to estimate the population proportion p is not appropriate..

In the movie Flatland A. Square visits Spaceland and from there obse.pdf

sumit082

In the movie Flatland A. Square visits Spaceland and from there observes many different lands Solution \'A. Square\' is referred to as a square. We know that square is a two dimensional figure. We also know that square is made up of infinitely many points. Since a point has zero dimensions and it doesn\'t occupy any real space. That is the reason why it cannot see the square. On the other hand, square is two dimensional, and it occupies infinitely many points, so it can see all those points. Since square can also be considered to contain infinitely many lines (which are one dimensional), so it can easily see all the line it contains. However, line can only see that part of the square which it occupies. So it can see the portion lying in one dimension only. The other portion that lies on the other dimension cannot be seen by the line. Since \'square\' as well as \'flat\' are two dimensional figures, so that can see each other quite well as they occupy each other. A tesseract is a four dimensional version of a square. For example square it two dimensional, cube is three dimensional and tesseract is 4 dimensional. Now if a tesseract meets a square in the spaceland, tesseract will be able to see all about square because tesseract occupies it completely. However, square won\'t be able to see the tesseract entirely. Square will only be able to see the part of the tesseract that lies on it, i.e. two dimensional part. Rest of the part of tesseract will not be accessible to the square. Hope it makes sense..

In the first quarter of 2009, President Obama pushed his massive fis.pdf

sumit082

In the first quarter of 2009, President Obama pushed his massive fiscal stimulus package of $862 (It was originally at $787 billion) through the Congress and later passed by the House and the Senate, whose centerpiece was spending most of this stimulus funds in repairing and building infrastructure in transportation, healthcare, science and technology, and education. Pres. Obama also urged to make a modest tax cut for middleincome families making a household income less than $250K per year (it has been modified to $400k starting from January 2013). The push for this combined package of spending and partial tax cut was also criticized by several opponents in politics, academia, and businesses on the ground that the spending was too large under government financing to balance the growing budget deficit and national debt that might threaten future economic stability of the country. A) What possible macroeconomic arguments might President Obama use to defend his $862 billion fiscal stimulus package as a part of his economic recovery plans? B) What were the macroeconomic arguments the critics might have expressed in their opposition to stimulus package as a bad economic policy, and not just for the US, but also for the world economy? Do they sound to have a trickle down adverse effect in the current or future financial stability in the US and the World economy, say later in 2013 and beyond? Do you think this issue is also related to the current political rhetoric between the GOP and Democrats on raising the tax rates for the wealthy making over $250K annually and leave the Bush Tax cut for the middle class (expired on Dec 31, 2012, with modification of extending the tax cut up to $400K per household)? With the new fiscal bill of President Obama passed by the US Congress on Jan 2nd of 2013, how would it affect the economy in the next two years starting from Jan 2013? Note: President Obama is expected to propose further stimulus package in his 2015 State of the Union Address of Jan 20, 2015 on the basis of the same principle for boosting the middle class economy. C) Recent data shows a sudden decline of RGDP growth rate in China after continuous robust economic growth for more than a quarter of century. In response to this early sign of recession, on April 19, 2015 the central bank of China has reduced its reserve requirement ratio by another 1% that it has started reducing since Nov 30, 2011. This is the second time since Feb 4, 2015 that the Central Bank of China reduced its RRR this year. In reaction to that biggest one time reduction of RRR was a sharp spike in stock market prices worldwide within hours. What would happen to the growth rate of the money supply in China if foreigners lost confidence in the Chinese Economy as a result of current uncertainty over the declining rate of economic growth and aggressive reduction of RRR by its Central Bank? Explain briefly. D)Using the Keynesian Cross model diagram (The diagram with 45 degree line by sp.

In the early 1990s, Cranston Dispensers, Inc. was quick to realize t.pdf

sumit082

In the early 1990s, Cranston Dispensers, Inc. was quick to realize that concern for the environment would cause many consumer product manufacturers to move away from aerosol dispensers to mechanical alternatives that pose no threat to the ozone layer. In the following decades, most countries banned the most popular aerosol propellants, first chlorofluorocarbons and then hydrocholrofluorocarbons. As the leading manufacturer of specialized pump and spray containers for a variety of products in cosmetics, household cleaning supplies, and pharmaceutical industries, Cranston experienced a rapid increase in sales and profitability after it made this strategic move. At that time, the firm focused much of its attention on capturing market share and keeping up with demand. For most of 20x4 and 20x5, however, Cranston’s share price was falling while shares of other companies in the industry were rising. At the end of fiscal 20x5, the company hired Susan McNulty as the new treasurer, with the expectation that she would diagnose Cranston’s problems and improve the company’s financial performance relative to that of its competitors. She decided to begin the task with a thorough review of the company’s working capital management practices. While examining the company’s financial statements, she noted that Cranston had a higher percentage of current assets on its balance sheet than other companies in the packaging industry. The high level of current assets caused the company to carry more short-term debt and to have higher interest expense than its competitors. It was also causing the company to lag behind its competitors on some key financial measures, such as return on assets and return on equity. In an effort to improve Cranston’s overall performance, Susan has decided to conduct a comprehensive review of working capital management policies, including those related to the cash conversion cycle, credit policy, and inventory management. Cranston’s financial statements for the three most recent years follow. Cranston Dispensers Income Statement ($ in thousands) Account 20x5 20x4 20x3 Sales 3,784 3,202 2,760 Cost of Goods Sold 2,568 2,172 1,856 Gross Profit 1,216 1,030 904 Selling & Administrative 550 478 406 Depreciation 247 230 200 Earnings Before Interest and Taxes 419 322 298 Interest Expense 20 25 14 Taxable Income 399 297 284 Taxes 120 89 85 Net Income 279 208 199 Cranston Dispensers Balance Sheet ($ in thousands) Account 20x5 20x4 20x3 Current Assets Cash 341 276 236 Accounts Receivable 722 642 320 Inventory 595 512 388 Total Current Assets 1,658 1,430 944 Net Fixed Assets 1,822 1,691 1,572 Total Assets 3,480 3,121 2,516 Current Liabilities Accounts Payable 332 288 204 Accrued Expenses 343 335 192 Short-term Notes 503 491 243 Total Current Liabilities 1,178 1,114 639 Long-term Debt 398 324 289 Other Long-term Liabilities 239 154 147 Total Liabilities 1,815 1,592 1,075 Owners’ Equity Common Equity 1,665 1,529 1,441 Total Liabilities & Equity 3,480 3,12.

In the 1980 census, Booneville had 3428 residents, and in the 1990 census, it had 2783. There were 178 births and 87 deaths during the decade between 1980 and 1990. What was the net input of people moving into Booneville? Realtors report that 187 people moved into Booneville between 1980 and 1990. How many people left? Solution 3428 + 178 births - 87 death = 3519 people +187 moved in = 3706 people by 1990 but only 2783 were found in consensus so 3706 - 2783 = 923 left town.

In recent years, a growing array of entertainment options competes for consumer time. By 2004, cable television and radio surpassed broadcast television, recorded mustic, and the daily newspaper to become the two entertainment media with the greatest usage (The Wall Street Journal, January 26, 2004). Researchers used a sample of 15 individuals and collected data on the hours per week spent watching cable television and hours per week spent listening to the radio. a. Use a .05 level of significance and test for a difference between the population mean usage for cable television and radio. What is the p-value? b. What is the sample mean number of hours per week spent watching cable television? What is the sample mean number of hours per week spent listening to radio? Which medium has the greater usage? Solution The null hypothesis tested is H0: There is no significant difference between the population mean usage for cable televisionand radio H1: There is significant difference between the population mean usage for cable television and radio Test Statistic used is T= d /s square root of n = , where d mean of difference, S the SD of the difference , n sample size Rejection criteria : Reject the null hypothesis, if the calculated value of t is greater than thecritical value of t . Details Test Statistics t = -2.3577 Critical value of t = ± 2.1448P value = 0.0335 Conclusion. Reject the null hypothesis. The sample provides enough evidence to support theclaim Television radioa MEAN 18.8 20 SD 5.230 5.24 SINCE MEAN VAKUE OF RADIO IS HIGH , WE CONCLUDE THAT RADIOHAS GREATER USAGE.

in recent general election there are arguements among strategists an.pdf

sumit082

in recent general election there are arguements among strategists and number crunchers from both parties that some polls unfairly sample more people from the other party than their proportion in reality. What kind of sampling method is used by those3 polisters? why? Solution The Washington Post and ABC News has a new national poll out today. It purports to show that Barack Obama has a 50% approval rating and that he would beat Mitt Romney in a head-to-head matchup. And heck, that might even be true, except for a couple of problems. First, this is a poll of general population adults rather than registered or likely voters, so it’s not even a proper polling type for the predictive outcome they claim. More importantly, though, the poll series has dropped its reporting of partisan identification within their samples. It’s the second time that the poll has not included the D/R/I split in its sample report, and now it looks as though this will be policy from this point forward. Since this is a poll series that has handed double-digit partisan advantages to Democrats in the past (for instance, this poll from April 2011 where the sample only had 22% Republicans), it’s not enough to just hear “trust us” on sample integrity from the Washington Post or ABC. One cannot determine whether Obama’s improvement in this series is a result of the State of the Union speech, as Dan Balz and Jon Cohen suggest, or whether it’s due to shifting the sample to favor Democrats more so than in previous samples. The same is true for the Post’s report that Obama “for the first time has a clear edge” over Romney head-to-head. One would need a poll of registered or likely voters to actually make that claim (one has to register to cast a vote, after all), and one would need to see the difference in partisan splits between this and other surveys in the series to determine whether the movement actually exists or got manufactured by the pollster. Essentially, the overall poll is worthless, and given the track record of this poll series, it’s easy to assume that the reason that the Post has ended its sample transparency is because they have something to hide. Among the Republicans and independents the Post did survey, Romney has a big lead over the rest of the field, 39/23 over Gingrich, with Santorum coming in at 16% and Paul at 15%. Since we don’t know the mix between Republicans and independents here, either, and we’re still dealing with adults in the middle of the primaries when the likely voter model should be used, this is also a worthless result..
