Question

Please explain, I dont really understand7. 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 a hypothesis testing, if the p-value is smaller than the preset significance level (e.g., 0.05), do we reject or fail to reject the null hypothesis?

    The Central Limit Theorem tells us that the sampling distribution of the sample mean can be approximated with a normal distribution for “large”n as n gets bigger, the sample data becomes more like the normal distribution if the data comes from an (approximately) normally distributed population, then the sample mean will also be (approximately) normally distributed the minimum variance unbiased estimator is the "best" estimator for a parameter

    Why is the Central Limit Theorem useful? [Q8P5.3] a. Because when the conditions for the CLT are met, it allows us to use a Normal distribution to approximate the distribution of the whole population, even if we don't know whether the population follows a Normal distribution. Because when the conditions of the CLT are met, it allows us to calculate the area in the tails of the population distribution and therefore the probability of obtaining an observation as or more...

    8. Using Minitab to illustrate the Central Limit Theorem (CLT), the CLT tells us about the sampling distribution of the sample mean. With Minitab we can easily "sample" from a population with known properties (4,0 , shape). a. Our population consists of integer values X from 1 through 8, all equally likely P(x) = 1/8; x = 1, 2, 3, 4, 5, 6, 7, 8 o = 2.29 Using methods from the beginning of Chapter 4 in the textbook, find...
