Question
A nutritionist claims that the mean tuna consumption by a person is 3.4 pounds per year. A sample of 80 people shows that the mean tuna consumption by a
person is 3.1 pounds per year. Assume the population standard deviation is 1.06 pounds. At a = 0.09, can you reject the claim?
(a) Identify the null hypothesis and alternative hypothesis.
_A. Ho: M ‡3.1
Ha: 4 = 3.1
_ D. Ho: M $ 3.1
Ha: H > 3.1
(b) Identify the standardized test statistic
= - 2.53 (Round to two decimal places as needed.)
(c) Find the P-value.
