4. Suppose that the average amount of money a student spends on
textbooks per semester at college campuses in the US is $500 with a
standard deviation of $100. Fairmont State University wants to know
if its students are spending that amount on textbooks. A random
sample of 75 SU students has been selected and their average
spending on textbooks was $400. Do a hypothesis test using α =
0.05.
