The sample statistics and theoretical values for each simulation are as follows:

a) Looking at the histograms in Exercise 4, at what sample size would you be comfortable using the Normal model as an approximation for the sampling distribution?

b) What does the Success/Failure Condition say about the choice you made in part a?
