Accepted Answer

Given,

	ANOVA
	Chi-Square Goodness of Fit
	One mean t-test
	One-mean z-test

	H_o:The mean ages for teenagers obtaining their drivers licenses are approximately the same average age across the country.
	H_o: At least one of the mean ages for teenagers obtaining their drivers licenses is different from the average age across the country.

	H_a: At least one of the mean ages for teenagers obtaining their drivers licenses is different from the average age across the country. .
	H_a:The mean ages for teenagers obtaining their drivers licenses are approximately the same average age across the country.

	Fail to reject the null hypothesis
	Reject the null hypothesis

	At the 0.10 level of significance, the mean ages for teenagers obtaining their drivers licenses are approximately the same average age across the country.
	At the 0.10 level of significance, the mean ages for teenagers obtaining their drivers licenses are not approximately the same average age across the country.
