Question

A nutritionist claims that the mean tuna consumption by a person is 3.8 pounds per year. A sample of 60 people shows that the mean tuna consumption by a person is 3.6 pounds per year. Assume the population standard deviation is 1.03 pounds. At = 0.06, can you reject the claim? (a) Identify the null hypothesis and alternative hypothesis OA. Ho : 3.6 0 D. Ho : > 3.6 Ha : > 3.8 0 E. Ho: #3.6 Ha : = 3.6 C. Ho : -3.8 Ha : $3.8 F. Ho : = 3.8 Ha: #3.8 Ha : > 3.6 Ha : 3.6 (b) ldentify the standardized test statistic z = 1 (Round to two decimal places as needed.) (c) Find the P-value (Round to three decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis

Explanation / Answer

a) Answer: Option F

b) z = (3.6-3.8)/(1.03/sqrt(60)) = -1.50

c) p(two sided) = 0.134

d) Option B
