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.

Use the Central Limit Theorem to find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution. The mean price of photo printers on a website is $243 with a standard deviation of $59. Random samples of size 26 are drawn from this population and the mean of each sample is determined. The mean of the distribution of sample means is _______.

1. In this problem, you are going to numerically verify that the Central Limit Theorem is valid even when sampling from non-normal distributions. Suppose that a component has a probability of failure described by a Weibull distri- bution. Let X be the random variable that denotes time until failure; its probability density is: for a 2 0, and zero elsewhere. In this problem, assume k 1.5, 100 a) Simulate drawing a set of N-20 sample values, repeated over M 200...
