Individuals filing federal income tax returns prior to March 31 received an average refund of $1,064. Consider the population of "last-minute" filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15).
a. A researcher suggests that a reason individuals wait until the last five days is that on average these individuals receive lower refunds than do early filers. Develop appropriate hypotheses such that rejection of H0 will support the researcher's contention.
H0: m is _______ (>, <, >=, <=, =, not equal to 1064)
Ha: m is _______(>, <, >=, <=, =, not equal to 1064)
b. For a sample of 400 individuals who filed a tax return between April 10 and 15, the sample mean refund was $910. Based on prior experience a population standard deviation of s=$1,600 may be assumed. What is the p-value (to 4 decimals)?
c. Using a=0.05, can you conclude that the population mean refund for "last minute" filers is less than the population mean refund for early filers? (Yes/No)
Answer the next three questions using the critical value approach.
d. Using a=0.05, what is the critical value for the test statistic? Enter negative value as negative number.
State the rejection rule: Reject a=0.05 if z is _________ (>, <, >=, <=, =, not equal to) the critical value.
Using a=0.05, can you conclude that the population mean refund
for "last minute" filers is less than the population mean refund
for early filers? (Yes/No)
