18.   Textbook Prices Heather Carielli is a former student of the author who earned a Mas- ter’s degree in statistics at the University of Massachusetts. When she randomly se- lected 16 new textbooks in the college bookstore, she found that they had prices with a mean of $70.41 and a standard deviation of $19.70. Is there sufficient evidence to warrant rejection of a claim in the college catalog that the mean price of a textbook at this college is less than $75?
