In 2009, the average starting salary for an individual right out of college with a bachelor’s degree in business was $49,400 per year. Suppose a 2014 study, which randomly sampled 48 individuals right out of college with a bachelor’s degree in business, showed an average starting salary of $51,620. Assume the population standard deviation is 7,810. Find the 80% confidence interval, find the upper (i.e., right endpoint.
