A study reports that recent college graduates from Connecticut face the highest average debt of $31,281 (forbes.com, September 18, 2019). A researcher from Pennsylvania wants to determine how recent undergraduates from that state fare. He collects data on debt from 40 recent undergraduates. Assume that the population standard deviation is $5,200. (You may find it useful to reference the z table.) a. Construct the 95% confidence interval for the mean debt of all undergraduates from Pennsylvania. (Do not round intermediate calculations. Round"
