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. O A. Ho: u>3.1 O B. Ho: HS3.1 Hai H> 3.1 O E. Ho: H>3.2 OC. Ho: H#3.1 Ha: H= 3.1 F. Ho:H=3.2 Ha: u53.1 OD.
