Question
Transcribed Image Text: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 3.8 pounds per year. Assume the population standard deviation is 1.08
pounds. At a = 0.04, can you reject the claim?
(a) Identify the null hypothesis and alternative hypothesis.
O A. Ho: H#3.8
H:p= 3.8
O B. Ho: H= 3.9
OC. Ho: u53.8
Ha: u#3.9
H: u> 3.8
O D. Ho: uS39
O E. Ho: >3.8
H: us3.8
OF. Ho: u> 3.9
H: p> 3.9
H: us3.9
(b) Identify the standardized test statistic.
z=(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.
O A. Fail
reject Ho. There is sufficient evidence to reject the claim that mean tuna consumption is equal to 3.9
O B. Reject Ho. There is not sufficient evidence to reject the claim that mean tuna consumption is equal to 3.9 pounds.
