A consumer group is planning to do 2 twosample t tests. In Test 1, they are going to put together a random sample of items at a jewelry store and compare the prices to a random sample of items at a bookstore, in order to see which store is more expensive. In Test 2, they are planning to compare a random sample of textbooks purchased at a campus bookstore to the same books purchased through an online bookseller, in order to see which store is more expensive.

(a) Determine which test is an independent- samples t test and which a pairedsamples t test.

(b) It sounds like each test is answering the same question, “Which store is more expensive?” Rewrite the questions so that they more accurately pose the question that the test answers.
