Question#1: Suppose we have selected a random sample of n = 36 observations from a population with mean equal to 80 and standard deviation equal to 6. It is known that the population is not extremely skewed. a. Sketch the sampling distributions for mean I. b. Find the probability that x will be larger than 82. Question#2: Consider the set (1,2,3} 1) Make a list of all samples of size 2 that can be drawn from this set ( Sample with replacement) 2) Construct the sampling distribution and the minimum for samples of size 2
