CHAP 13 OIS 3440-STAT Question A chi-square test for goodness-of-fit is used to test whether or not there are any preferences among 3 brands of peas. If the study uses a sample of n = 60 subjects, then the expected frequency for each category would be: 60 20 33 30 Question, When the variables of interest are both categorical and the decision maker is interested in determining whether a relationship exists between the two, a statistical technique known as contingency analysis is useful. True False Question A survey was recently conducted in which males and females were asked whether they owned a laptop personal computer. The following data were observed: Males Females Have Laptop 120 70 No Laptop 50 60 Given this information, if an alpha level of .05 is used, the test statistic for determining whether having a laptop is independent of gender is approximately 14.23. True False Question In conducting a test of independence for a contingency table that has 4 rows and 3 columns, the number of degrees of freedom is 11. True False Question If a contingency analysis test is performed with a 4 × 6 design, and if alpha = .05, the critical value from the chi-square distribution is 24.9958 True False Question A walk-in medical clinic believes that arrivals are uniformly distributed over weekdays (Monday through Friday).

write a research paper about happy family novel by Wendy lee . Solution Adoption is a beautiful and noble calling. Yet, it is imperfect, with biological parents, their extended families, and even whole nations left to mourn to loss of that child to some degree or another. At least, this is one of the points Wendy Lee elegantly and politely makes in Happy Family. I truly enjoyed this novel. Lee\'s writing is gentle and fluid.

Which intermolecular porcess primarly drives the formation of a bilayer when phospholipids are added to water? Which intermolecular porcess primarly drives the formation of a bilayer when phospholipids are added to water? A-Lipids cause water to arrange in an ordered, unfavorable cage-like structure. B-Forcing lipids into a bilayer reduces this effect. C-The ordered arrangement of a bilayer is more favorable than the disordered state of individual free-floating phospholipids. D-A bilayer arrangement maximizes the strength of hydrophobic interactions among phospholipids. E-Phospholipids self-assemble inot a bilayer due to the strong affinity they have for each other. Solution Thanks for your query. As the lipid bilayer forms the surface of the cell. there is an important point that we have to understand here., That is the lipid cell is hydrophilic on one end and hydrophobic on the other end. Therefore, the hydrophobic ends of both cells join in the center of the lipid bilayer and the hydrophilic ends expose themselves to the outer surface and the inner surface. Since they are hydrophilic they can easily interact with the fluids they are exposed to unlike the hydrophobic ends. Therefore the correct option is D Thanks.

Which of the following is an example of a translocation? a chromosome containing the mutant sickle cell allele Two chromosomes have experienced breaks at their terminal ends (e.g., chromosome 6 and 18), and during the rejoining process, the ends get switched. The end of chromosome 6 becomes attached to chromosome 15 and vice verse an occurrence of nondisjunction at meiosis I an occurrence of nondisjunction at meiosis Solution Answer: Translocations are chromosomal abnormalities which occur when chromosomes break and the fragments rejoin to other chromosomes. It is of 2 types which are reciprocal and non- reciprocal translocation. reciprocal one show normal phenotype as compare to the other one, so option second is most appropriate example of chromosomal translocation..

What is simplicity and how does it bear on the acceptability of a scientific hypothesis? Solution Simplicity - simpler means fewer assumptions. Consider Newtons mechanics and copernican hypothesis . They both stand as examples of generality and simplicity. Newton with help of previous general set of laws explained laws of motion for terrestial and heavenly bodies. Copernicus explained the same observational data with simpler assumptions. The virtues are not independent and in some cases it overlaps. In some cases generalisation will be simplification. Simplicity is used for describing philosophical theories . In general if a hypothesis is more simpler it can be confirmed . In some cases precision overlaps simplicity. The reality is part of quine pervasive scientific realism. Quine quotes for simplicity. Quine also quotes that different classes or groups can be clearly dealt only if is in simpler explanatory view and relative simplicity of the system. Hence a scientific theory should not be generalised but should be in simplified form..

What’s the difference between soluble and insoluble fiber? Why is fiber indigestible? After all, isn’t cellulose just a string of glucose molecules, similar to amylose? What are some of the benefits of increasing fiber intake? How does fiber confer these benefits? What are some of the potential pitfalls of consuming excess fiber? How does fiber confer these detriments? What are the general recommendations for fiber intake? We refer to some of our fibers as prebiotics. What does that term really mean? How does a prebiotic aid gut health? Solution What’s the difference between soluble and insoluble fiber? ANS: In short soluble fibres dissolve in water and insoluble fibres do not. Soluble fibre makes our food more viscous when in a digestive tract. Soluble fibre traps food components thus making them less absorbable. Insoluble fibre absorbs water for example how dry sponge expands after soaking up water. Insoluble fibres are helpful in treating constipation. Why is fiber indigestible? After all, isn’t cellulose just a string of glucose molecules, similar to amylose? ANS: What makes fibre indigestible is the lack of enzymes in humans to break down the glycosidic bond in fibre. What are some of the benefits of increasing fiber intake? ANS: Benefits of fibre intake include: gastrointestinal disorders lowering cholesterol levels lowering the risk of colon cancer weight loss How does fiber confer these benefits? ANS: fibre has three mechanisms of action, which are bulking, viscosity and fermentation. Fibres can use all three mechanisms or only one. Bulking fibres absorb water and increase stool weight and regularity. Bulking fibres can be minimally fermented or not fermented. Viscous fibres thicken the content of the intestinal tract . They mix with water and form a gelatinous mass. Depending on the type of viscous fibre, they are minimally, partially, completely fermented or not fermented at all. Fermentable fibres are used as food source for the microbes that exist on our large intestine. What are some of the potential pitfalls of consuming excess fiber? ANS: As fibre is not digested, too much fibre causes the digestive tracts to process it slowly, it can lead to bloating, constipation, abdominal discomfort and gas. If constipation is prolonged, it can lead to intestinal blockage. during intestinal blockage there can be malabsorption and accumulations of toxins in the body..

The U.S. government subsidizes flood insurance because those who want to buy it live in the flood plain and cannot get it at reasonable rates. What inefficiency does this create Solution As Hurricane Sandy continues to batter the Eastern seaboard of the U.S., one thing is for certain: insurance companies will be ponying up for billions of dollars in property damage caused by high winds. Last year’s Hurricane Irene cost insurance providers more than $4 billion in damage claims, with flood-insurance payments totaling nearly $1.3 billion. But what many Americans may not know is that this $1.3 billion was a bill footed by the federal government, which underwrites the vast majority of flood insurance across the nation. Historically, insurance companies have been wary of offering flood insurance to homeowners because the risks associated with flood insurance are difficult to forecast, so any private insurance that had been offered was prohibitively expensive for average homeowners. But in the 1960s, frequent flooding of the Mississippi River was driving up the costs of federal disaster-relief programs. In an effort to reduce these costs,Congress set up the National Flood Insurance Program (NFIP) to provide flood insurance to the general public and promote effective floodplain management. Under the program, homeowners in certain areas of the U.S. are required to buy flood insurance, and communities that hope to benefit from the program have to enforce city-planning regulations set out by FEMA, which manages NFIP. (MORE: Banks Waive Fees for Residents in Path of Hurricane Sandy) Though the program has been effective at making flood insurance widely available, a growing chorus of critics from environmentalists to libertarians has been attacking it for encouraging homeowners to build recklessly in areas that are prone to flooding. For instance, Ira Stoll wrote yesterday in the New York Sun: “Hurricane casualties are partly the result of unintended consequences of government actions: without federal flood insurance, many fewer people would take the risk of living in low-lying areas vulnerable to storm surges.” There is evidence to support the view that the government is actually encouraging citizens to live in areas most in danger of flood damage. According to a 2010 report issued by the Institute for Policy Integrity, Congress has historically set the premium rate too low for flood insurance — effectively subsidizing building in flood-prone areas at the expense of taxpayers at large. This practice has helped drive the fund $19 billion in debt, caused mostly by the unusually severe damage caused by Hurricane Katrina. In addition, the report argued that the environmental effects of the federal government’s flood- insurance policy may be more severe than the financial effects. According to the report: “River basins and coastal zones provide natural purification of water and wastewater; erosion control and weather mitigation; and habitat for fish and wildl.

What was Darwin\'s big idea? How does it differ from previous ideas explaining the diversity of life on Earth? What is the \'Scala Naturae\', who advanced this concept and why was it so widely accepted? What is \'Systema Naturae\', who advanced this concept and why so accepted? Who are these people did we talk about them? How are their ideas relevant to a conversation about evolution? Malthus, Linneaus, Hutton, Lyell, cuvier, Lamarck, Aristotle, Darwin, Mendel, Wallace What did Lamarck propose as an explanation for how organisms change over time? Explain how Lamarck\'s ideas are not supported by evidence? Descent with modification by means of natural selection explains the adaptations of organisms and the unity and diversity of life What did Darwin do that most influenced his worldview (what is a worldview)? What were the critical observations Darwin made on his voyage of discovery? What two main ideas did Darwin develop in the \"Origin of Species\"? What is natural selection? (Look at the lecture powerpoints to answer the question) What are three main points and important considerations regarding natural selection? What is an adaptation? What are the two observations and two inferences that explain how natural selection leads to adaptive evolution? What role did artificial selection play in the development of Darwin\'s logic for natural selection? What does the theory of evolution suggest will happen when environments favoring one adaptation change? Solution Ques-1: What were the prevailing thoughts about the young Earth and the organisms on it prior to Darwin The prevailing thoughts about the young Earth and the organisms on it prior to Darwin are creatures were created by supernatural power & human are going to control these creatures and populations are unchanging on the young Earth. Theory of evolution of “Darwin” has produced specific impact on the imperialism and biblical view of origin of the species finally affected contemporary philosophical views of religion & creation. These views have changed socio- economical perspectives in the society about the culture finally changed the “religious views of humans that “human race has evolved from God’s creation & God’s image”. Ques-2: What was Darwin\'s big idea? Answer: Darwin theory of evolution is completely based on genetic variations and natural selection operating on the species to acquire adaptations followed by unfit species are going to extinct. However, here the extinction is not based on designer as it is due to nature. Nature selects species, which are fit into it followed by elimination that is unfit in nature. It is different from previous ideas of Earth species diversity, in which creation was completely relies upon myths and God, the “religious views of humans that “human race has evo.
