What is the difference between the histograms when the population is Normal (question 1) and when the population is Negative Exponential (question 2)? 3. What will be the shape of the sampling distribution if we generate it with a sample size of 40? (2 pt) +8 6% 10:35 PM Fri Sep 20 - a. Frequency 1000 0 Frequency 1. Generate the sampling distribution for the sample mean by setting the population distribution to Normal, the statistic the mean, the mean Mu of 100, the standard deviation sigma of 15, the sample size to 5, and the samples to draw at a time to 1000.
