The agent selected a sample of22 rental properties and found their mean to be $19.25 per square foot, with asample standard deviation of $3.45 per square foot. Test the claim at alpha = 0.05. Use the P-value method to evaluate/compare with the given alpha (0.05).

For question #18,give your calculated value for "t", rounding to the hundredths place.

For question #19 (multiple choice), choose between what two areas your calculated t-value (when converted to P-value) falls.

For question #20, answer True or False with regard to rejecting the null hypothesis.Hint: this is a two-tailed test!!
