A nutritionist claims that the mean tuna consumption by a person is 3.3 pounds per year. A sample of 70 people shows that the mean tuna consumption by a person is 3.1 pounds per year. Assume the population standard deviation is 1.05 pounds. At a = 0.06, can you reject the claim? Ha: p> 3.1 H3: µs3.1 H, µ#3.3 a (b) Identify the standardized test statistic. z= - 1.59 (Round to two decimal places as needed.) (c) Find the P-value. 0.112 (Round to three decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. O B. Fail to reject Ho. There is not sufficient evidence to reject the claim that mean tuna consumption is equal to 3.3 pounds. A. Reject Ho- There is sufficient evidence to reject the claim that mean tuna consumption is equal to 3.3 pounds. O C. Fail to reject Ho. There is sufficient evidence to reject the claim that mean tuna consumption is equal to 3.3 pounds. O D. Reject Ho There is not sufficient evidence to reject the claim that mean tuna consumption is equal to 3.3 pounds.
