A consumer watchdog group randomly samples n = 64 servings and finds a sample mean of 615 mg with a sample standard deviation of 32 mg.Answer the following:1. State the null and alternative hypotheses.2. Calculate the standard error of the mean.3. Compute the z-statistic for this test.4. At alpha = 0.05, should the watchdog group reject the nutritionist’s claim?5. What is the conclusion at alpha = 0.01?6. Is this test exact or approximate? Justify your answer.
