1.On the Road Again, Inc. maintains a large fleet of rental cars. They want their fleet to have an average of at least 25 mpg. They will determine this based on an appropriate 1-sided hypothesis test with a = 0.05. They sample 49 cars at random and find a sample mean of 25.88 mpg with a sample standard deviation of 2.90 mpg. Compute by hand the appropriate test statistic and give the conclusion of the test. (Use Minitab to get p-value.)

2. A consumer protection agency is interested in whether there is a difference in calories between Pudlagers light beer and their regular beer. They randomly sample 64 bottles of each type of beer. The light beer has a sample average of 119 calories with a sample standard deviation of 5.8 calories. The regular beer has a sample average of 125 calories with a sample standard deviation of 7.4 calories. The critical value* for an appropriate test at the 5% level is 1.979. Based on this, what is the conclusion of the hypothesis test? (Using the critical value, compute the test statistic by hand to reach the conclusion. Then confirm with Minitab.)
