A nutritionist claims that the mean tuna consumption by a person is 3.5 pounds per year. A sample of 60 people shows that the mean tuna consumption by a person is 3.1 pounds per year. Assume the population standard deviation is 1.22 pounds. At a = 0.03, can you reject the claim?

Transcribed Image Text:A nutritionist claims that the mean tuna consumption by a person is 3.5 pounds per year. A sample of 60 people shows that the mean tuna consumption by a person is 3.1 pounds per year.
Assume the population standard deviation is 1.22 pounds. At a = 0.03, can you reject the claim?
(a) Identify the null hypothesis and alternative hypothesis.
O A. Ho: µ = 3.5
OC. Ho: u> 3.1
O B. Ho: µ#3.1
Ha: µ= 3.1
Hạ: µ#3.5
Hai u53.1
O D. Ho: µ> 3.5
Hai us3.5
O E. Ho: us3.1
Ha: µ>3.1
OF. Ho: us3.5
Ha: µ> 3.5
(b) Identify the standardized test statistic.
(Round to two decimal places as needed.)

Assume the population standard deviation is 1.22 pounds. At a = 0.03, can you reject the claim?
3.5 pounds per year. A sample of 60 people shows that the mean tuna consumption by a person is 3.1 pounds per year.
(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. Reject Hn. There is not sufficient evidence to reject the claim that mean tuna
O B. Fail to reject Ho. There is not sufficient evidence to reject the claim that mean tuna
consumption is equal to 3.5 pounds.
consumption is equal to 3.5 pounds.
O D. Fail to reject Ho. There is sufficient evidence to reject the claim that mean tuna
OC. Reject Hn. There is sufficient evidence to reject the claim that mean tuna consumption
is equal to 3.5 pounds.
consumption is equal to 3.5 pounds.
