You want to know if there is a difference in price between imported and domestic beers. You go to your local supermarket and record the sales price and country of origin of 68 different beers. A t-test is run, the results of which appear below.
1.Why would it be better to use a one-tailed test in this case?
2.You selected a one-tailed test, what are the null and experimental hypotheses (H0 and H1)?
3.In the beer price study, what is the critical value of t used in a one-tailed test?
4.Is there a significant difference between the price of domestic versus imported beers? What does this mean?
Word document attached answers questions about one-tailed hypotheses, critical values and conclusion.
