Which one of the following statements is true?

A. Because the p-value is greater than , we fail to reject the null hypothesis and cannot conclude that the average monthly rate for an assisted-living facility is not equal to $3,300.

B. Because the p-value is greater than , we fail to reject the null hypothesis and conclude that the average monthly rate for an assisted-living facility is equal to $3,300.

C. Because the p-value is less than , we fail to reject the null hypothesis and conclude that the average monthly rate for an assisted-living facility is not equal to $3,300.

D. Because the p-value is less than , we reject the null hypothesis and conclude that the average monthly rate for an assisted-living facility is not equal to $3,300.
