A nutritionist claims that the mean tuna consumption by a person is 3.5 pounds per year. A sample of 50 people shows that the mean tuna consumption by a person is 2.9 pounds per year. Assume the population standard deviation is 1.23 pounds. At =0.05, can you reject theclaim?

(b) Identify the standardized test statistic.

z=
