For this Assignment, you are working at a firm that conductsindependent testing for heavy industry. Recently, an automobilemanufacturer has been in the news for complaints about the highwaygas mileage of their latest model minivan. You receive a contractfrom a consumer action group to test and write a report on thecompany’s claim that its minivans get 28 miles per gallon on thehighway. The car company agrees to allow you to select randomly 35low-mileage fleet minivans to test their highway mileage. Your testresults gave you the following data:

           29.7     24.5    27.1     29.8    29.2     27.0    27.8     24.1     29.3

           25.9     26.2    24.5     32.8    26.8     27.8    24.0     23.6     29.2

           26.5     27.7    27.1     23.7    24.1     27.2    25.9     26.7    27.8               

           27.3     27.6    22.8     25.3    26.6     26.4    27.1     26.1

List the null and alternative hypotheses for the two-tail testfor the mean. Calculate the observed value of the test statisticand the associated p-value.

Is the observed test statistic in the critical region? Is thep-value higher or lower than your alpha?

List the null and alternative hypotheses for the one-tail testof the mean. Calculate the observed value of the test statistic andthe associated p-value.

Is the observed test statistic in the critical region? Will thep-value be higher or lower than your alpha?
