About 40% of the general population ddonate their time and energy to community projects. suppose 15 people have been randomly selected fron a community and each asked if they donated their time and energy to community projects. Let x be the number of them that do donate their time and energy to community projects. Find the probability that more than seven of the15 do donate their time and energy to community projects. Solution Given X~Binomial(n=15, p=0.4) P(X=x)=xC15*(0.4^x)*(0.6^(15-x)) SO the probability is P(X>7)=P(X=8)+P(X=9)+...+P(X=15)=0.2131032.

Abigail, Bart, Carol, Dan, Ehud, Fred, Golda, Hiro, and Juan are to be seated at a circular table. As usual, two seating arrangements are considered different exactly when someone has a different person to his or her right. If Fred can not be seated next to Ehud or Golda, how many different seating arrangments are possible? Thanks in advance Solution It doesn\'t matter where the first person sits; that person is a frame of reference. Let\'s have Abigail be the frame of reference. Bart then has 8 possible choices for where he can sit. Carol has 7. Dan has 6. Ehud has 5. Fred (we\'ll get back to him later). Golda has 4, Hiro 3, and Juan 2. Fred then is left with one spot left. 2/9 of this time (on average), he will be next to Ehud, Golda, or both of them. So, if we take 8! then multiply that by 7/9, we\'ll get how many arrangements there are at the table total. 8! * 7 / 9 = 31360..

ABC Corp. has a fixed rate asset for which the firm receives an interest rate of 5%. The firm enters into an interest rate swap on the same notional principal as the fixed rate debt. In the swap, the firm pays 4% and receives LIBOR. What is the effective cash inflow that the firm receives with the interest rate swap? a. 4% b. 5% c. 6% d. LIBOR+1% e. LIBOR-1% Solution Interest received = 5% pays = 4% effective cash inflow = 5%-4% = 1% = LIBOR + 1%.

A.What is the sensitivity of self-reported smoking status? Solution Assessment of validity of self-reported smoking status by Suzy L. Wong, Margot Shields, Scott Leatherdale, Eric Malaison and David Hammond The health risks associated with cigarette smoking are well-documented and widely recognized—cancer, respiratory illness, heart disease, and stroke.1-3 In Canada, smoking contributes to more than 37,000 deaths a year.4 Tobacco-related health care expenditures amount to billions of dollars annually, with additional indirect costs such as lost productivity, longer-term disability and premature death.4 Self- reported data are typically used to monitor trends in cigarette smoking.5-7 However, estimates based on self-report, particularly of socially undesirable behaviours, are subject to reporting biases.8 The widespread implementation of legislation prohibiting smoking in workplaces and public areas9 and prominent health warnings on cigarette packages may reinforce the perception of smoking as socially undesirable, and thereby increased the tendency to underreport over time. To validate self-reported smoking status, the urinary concentration of cotinine, a widely accepted objective measure of exposure to tobacco smoke,10 has been used. Cotinine is the major metabolite of nicotine, with a half-life of about 16 to 20 hours.11 Because of its high sensitivity and specificity, cotinine is considered to be an accurate quantitative measure of recent exposure to tobacco smoke.12 Compared with estimates based on cotinine concentration, smoking prevalence based on self-report, is generally lower,13 although the extent of the difference varies by country.14 The validity of self-reported cigarette smoking data have yet to be determined for Canada. Thus, this study compares estimates of the prevalence of cigarette smoking based on self-report with estimates based on urinary cotinine concentrations. The data are from the 2007 to 2009 Canadian Health Measures Survey, which included self-reported smoking status and the first nationally representative measures of urinary cotinine. Methods Data source The Canadian Health Measures Survey (CHMS) is a nationally representative survey of the household population. Data for cycle 1 were collected from March 2007 through February 2009 at 15 sites across the country for respondents aged 6 to 79. Full-time members of the Canadian Forces and residents of Crown lands, Indian reserves, institutions and certain remote regions were excluded. The sample represented approximately 96% of the population.15 The CHMS consisted of a household interview during which information about socio- demographic characteristics, health and lifestyle was gathered. This was followed by a visit to a mobile examination centre where direct measurements, including the collection of urine samples, were taken. Of the households selected for the survey, 69.6% agreed to participate. One or two members of each responding household were invited to take p.
