A nutritionist claims that the mean tuna consumption by a person is 3.2 pounds per year. A sample of 90 people shows that the mean tuna consumption by a person is 3.1 pounds per year. Assume the population standard deviation is 1.12 pounds. At a = 0.07, can you reject the claim? (a) Identify the null hypothesis and alternative hypothesis. OA. Ho: H>3.1 OB. Ho: us3.1 O C.
