Question

A major producer of ice cream would like to test the hypothesis that the average American consumes more than 17 ounces of ice cream per month. A random sample of 25 Americans was found to consume an average of 17.2 ounces of ice cream last month. The standard deviation for this sample was 3.9 ounces. The producer would like to set α=0.10. What is the test statistic for this hypothesis test?

proportion of Americans who think unions have a positive effect on
schools has decreased this year when compared to last year. A
random sample of 160 Americans last year found that 48 felt unions

The CEO of the Jen and Benny's ice cream company is concerned
about the net weight of ice cream in their 50 ounce ice cream tubs.
He decides that he wants to be fairly sure that the mean weight of
these ice cream tubs (μ) is greater than 53 ounces. A hypothesis
test is conducted with the following hypotheses:
H0: μ = 53
Ha: μ > 53
The level of significance used in this test is α = 0.05. A...
