The executive salaries listed in the prior What Do You Think? are
310,000,
350,000, and
425,000. Assume that these three are a random sample.

a. What is the probability that the next draw from this population is larger than
310,000?⁵

b. Find a 50% prediction interval for the next random draw from this population.⁶

c. Is this the only possible 50% interval, or are there others?⁷
