Question 1: Individuals filing federal income tax returns prior to March 31 received an average refund of $1056. Consider the population of “last-minute” filers who mail their tax return during the last five days of the income tax period. A sample of 400 “last-minute” filers resulted in a sample mean refund of $910. Based on prior experience the IRS states the standard deviation is $1600. Is there evidence at a 5% level of significance that “last-minute” filers on average received different refunds than do early filers?
