1. The Department of Transportation would like to test the hypothesis that the average age of cars on the road is less than 10 years. A random sample of 50 cars had an average age of 9.5 years. It is believed that the population standard deviation for the age of cars is 3.4 years. The Department of Transportation would like to set = 0.10. The conclusion for this hypothesis test would be that because the test statistic is

A. more than the critical value, we can conclude that the average age of cars on the road is less than 10 years.

B. more than the critical value, we cannot conclude that the average age of cars on the road is less than 10 years.

C. less than the critical value, we can conclude that the average age of cars on the road is less than 10 years.

D. ess than the critical value, we cannot conclude that the average age of cars on the road is less than 10 years.

2. The p-value for a hypothesis test is defined as the probability of observing a

		A. critical value at least as extreme as the one selected for the hypothesis test, assuming the null hypothesis is true.
		B. critical value at least as extreme as the one selected for the hypothesis test, assuming the null hypothesis is false.
		C. sample mean at least as extreme as the one selected for the hypothesis test, assuming the null hypothesis is true.
		D. population mean at least as extreme as the one selected for the hypothesis test, assuming the alternative hypothesis is true.
