It is believed that the median annual starting salary of a freshman engineering graduate is $40,000. If we record the starting salary of a random sample of 100 recent engineering graduates, then

a. Find the sampling distribution (theta) of the proportion of fresh engineering graduates who started with an annual salary of less than $40,000.

b. Find the approximate probability that at least 60% of the engineering graduates started with an annual salary of more than $40,000.
