A nutritionist claims that the mean tuna consumption by a person is 3.9 pounds per year. A sample of 80 people shows that the mean tuna consumption by a person is 3.6 pounds per year. Assume the population standard deviation is 1.06 pounds. At α=0.04, can you reject the claim? (a) Identify the null hypothesis and alternative hypothesis. A. H0: μ>3.9 Ha: μ≤3.9 B. H0: μ>3.6 Ha: μ≤3.6 C. H0: μ=3.9 Ha: μ≠3.9 Your answer is correct. D. H0: μ≤3.9 Ha: μ>3.9 E. H0: μ≠3.6 Ha: μ=3.6 F. H0: μ≤3.6 Ha: μ>3.6 (b) Identify the standardized test statistic. z=negative 2.53−2.53 (Round to two decimal places as needed.) (c) Find the P-value. enter your response here (Round to three decimal places as needed.)
