15. An author has written 5 children's books. The number of pages in these books are 64, 65, 73, 74, and 76. a. List all 10 possible SRSS of size n=3, calculate the median number of pages for each sample, and display the sampling distribution of the sample median on a dotplot.

b. Show that the sample median is a biased estimator of the population median for this population.

c. Describe how the variability of the sampling distribution of the sample median would change if the sample size was decreased to n=2.
