2. Evaluate the following statement. To answer this question please state the Central Limit Theorem and explain why central limit theorem is so important. The samples mean of a random sample of n observations from a normal population with mean u and variance o2 is a sampling statistics. The sample mean is normally distributed with mean u and variance oʻ/n due to central limit theorem.

Making Reference to the Central Limit Theorem, explain why we expect many continuous traits in natural populations to have distributions that are nearly normal. Explain the main idea behind how GWA is carried out and what properties differentiate GWA mapping from classical linkage mapping.

7. True or False? The central limit theorem tells us that as the sample size increases, the sampling distribution of the sample mean approaches an approximately normal distribution REGARDLESS OF the original population data distribution. 8. True or False? Student t-distribution, regardless its degree of freedom, has heavier tails than the standard normal distribution. 9. In a hypothesis test we always assume the hypothesis unless we have sufficient evidence for the hypothesis 10. In...

CLT = Central Limit Theorem
Q5 Consider a problem of estimating the difference of proportions for two populations. In sample 1, out of n subjects, Si of them are "successes" and the rest are "failures". In sample 2, out of n2 subjects, S2 of them are "successes" and the rest are "failures". It is known that Si~ B(ni,P) and S2 ~ B(n2, p). We are interested in estimating P1 - P2. 1. Denote fi =...

3. Applying the central limit theorem Suppose you are a television network executive interested in how a new pilot show, Statistics, will be received by the general U.S. television-viewing population. You hire several market research firms; each recruits a random sample of television viewers and asks them to watch the pilot of Statistics. Each firm then gathers 25 respondents and asks each of them, "On a scale of 1 to 10, where 1 means you'll never watch Statistics again, and...
