Toll Brothers is a luxury home builder that would like to test the hypothesis that the average size of new homes exceeds 2,400 square feet. A random sample of 36 newly constructed homes had an average of 2,560 square feet. Assume that the standard deviation of the size for all newly constructed homes is 500 square feet. Toll Brothers would like to set α = 0.1. Use the critical value approach to test this hypothesis.

The average natural gas bill for a random sample of 64 homes in the 19808 zip code during the month of March was $405.30 with a population standard deviation of $42.50. The critical value (z score) for a 95% confidence interval around this sample mean is ________.

Use the p-value approach to solve previous question.

The federal government would like to test the hypothesis that the average age of men filing for Social Security is lower than the average age of women set using α = 0.05 with the following data: ​                                                Men                 Women Sample mean                          63.5 years        64.6 years Sample size                             35                    39 Population standard deviation 3.0 years          3.5 years   If Population 1 is defined as men and Population 2 is defined as women, the correct hypothesis statement for this hypothesis test would be
