A liquid dietary product implies in its advertising that use of the product for one month results in an average weight loss of at least 3 pounds. Eight subjects use the product for one month, and the resulting weight loss data are reported below. Use hypothesis-testing procedures to answer the following questions.

(a) Do the data support the claim of the producer of the dietary product with the probability of a type I error set to 0.05?
(b) Do the data support the claim of the producer of the dietary product with the probability of a type I error set to 0.01?
(c) In an effort to improve sales, the producer is considering changing its claim from €œat least 3 pounds€ to €œat least 5 pounds.€ Repeat parts (a) and (b) to test this new claim.
