← A study commissioned by a clothing manufacturer measured the Waist Size of 250 men, finding a mean of 36.33 inches and a standard deviation of 4.02 inches. To explore how the mean might vary from sample to sample, they simulated by drawing many samples of size 2, 5, 10, and 20, with replacement, from the 250 measurements. The summary statistics for these simulations are shown below. Answer parts a through d below. Click the icon to view the summary statistics table. Click the icon to view the histogram of the measurements and histograms of the sample means for each simulation. a) According to the Central Limit Theorem, what should the theoretical mean and standard deviation be for each of these sample sizes?

This histogram shows the heights of 20 students in a statistics class. Explain why it is not appropriate to find summary statistics for this distribution. Frequency 4- 3- 2- 1- T 0+ 60 65 70 75 Height (Inches) Choose the correct answer below. OA. Since there appear to be two modes, this data probably represents men and women and should be split into those two groups before finding any summary statistics. OB. The number of data values is too small for summary statistics to be meaningful. OC. Since the data appear to be bimodal, no other measures of center or spread can be calculated. OD. Since the distribution is not symmetric, summary statistics would be meaningless.
