Answer to Problem 6E

Yes, it reasonable to conclude that more high-schoolers have cars.

Explanation of Solution

It is given in the question that a survey investigating whether the proportion of today’s high school seniors who own their own cars is higher than it was a decade ago finds a P-value of $0.017$ . Thus, based on a P-value $0.017$ , there is strong evidence that the percent of today’s high school seniors who own their cars is higher than it was a decade ago. Thus, yes, it is reasonable to conclude that more high-schoolers have cars.
