Question 19 (8 points) Determine in each of the following situations whether the Central Limit Theorem applies in order to conclude that sampling distribution of the sample mean, that X-NI 7-N (M, ) For each distribution, determine whether CLT applies. If it does not, then enter NA as your answer in the blank number that corresponds to the distribution number. If it does, then enter the shape of the sample means as your first item in a list, the mean...
1. Three randomly selected households are surveyed. The numbers of people in the households are 3, 4 and 11. Assume that samples of size n=2 are randomly selected with replacement from the population of3, 4, and 11. Listed below are the nine different samples. Complete parts (a) through (c).3,3 3,4 3,11 4,3 4,4 4,11 11,3 11,4 11,11a.

Use the population of ages {56, 49, 58, 46} of the four U.S. presidents (Lincoln, Garfield, McKinley, Kennedy) when they were assassinated in office. Assume that random samples of size n = 2 are selected with replacement. 1. List the 16 different samples. For example, the samples for age 56 would be 56, 56 56, 49 56, 58 56, 46. 2. After listing all 16 samples, find the mean of each sample, then construct a table representing the sampling distribution...
