Refer to the Real Estate data, which report information on the homes sold in Goodyear, Arizona, last year. The housing market changed a lot recently, and so you want to assess the accuracy of some assumptions your company has been working from. Below are the assumptions your company already has and the alternate assumptions you think may be true now.

1. Your company assumes the mean selling price of a home is $220,000. You believe it's now more that $220,000.

2. Your company assumes the mean size of a home is 2,100 square feet. You believe it's now more than 2,100 square feet.

3. Your company assumes that 60% of homes have an attached garage. You believe it's now more than 60%.

4. Your company assumes that 30% of the homes have a pool. You believe it's now more than 30%.

Use the .05 significance level to test your assumptions. Write your conclusions in a paragraph-form memo to your company. Be sure to explain any statistical vocabulary you use in terms they will understand.
