5.14 Comparing sampling distributions. Refer to the previous exercise.

  1. (a) How do the centers of your two histograms reflect the differing truths about the two populations?

  2. (b) Describe any differences in the shapes of the two histograms. Is one more skewed than the other?

  3. (c) Compare the spreads of the two histograms. For which population is there less sampling variability?

  4. (d) Suppose instead that the population proportions were 0.6 and 0.8, respectively. Describe how the sampling distributions of would differ from those constructed in Exercise 5.13.
