The U.S. Census Bureau reported that the average area of U.S. homes built last year was 2,337 square feet. A simple random sample of 65 homes built this year had an average area of 2,259 square feet, with a standard deviation of 184 square feet. Assume the population data is approximately normally distributed. Test the claim that the average square feet of homes built this year is greater than last year by conducting a hypothesis test at the 0.01 significance level. Step 1: Select the 5 options below in Step 1 that are applicable for the problem on this page. Step 2: Select the 1 set of appropriate hypothesis statements in Step 2 for this problem--out of the three sets provided below. Step 3: Select the 2 items in Step 3 that represent the appropriate p-value and decision for the test results. Step 4: Pick the 3 correct answers below in Step 4 to fill in the blanks The result of the homes is significantly the claim that the average square feet than the reported
The result of the homes is significantly value of the claim that the average square feet than the reported Select 11 correct answer(s) Step 1: SRS? Yes Step 1: SRS? No Step 1: n=0.05 Step 1: n=184 Step 1: n=65 Step 1: n > 30 -- Yes Step 1: > 30 -- No
Step 1: ND -- Yes Step 1: ND -- No Step 1: Assumptions are met? Yes Step 1: Assumptions are met? No Step 2: H : j = 2,337 sq. ft. HA: u > 2,337 sq. ft. Step 2: H : p = 2,337 sq. ft. HA: μ< 2, 337 sq. ft. Step 2: H : p = 2,337 sq. ft. HA: u 72,337 sq. ft.
Step 3: p= 0.0006 Step 3: p = 0.9994 Step 3: p= 0.0011 Step 3: Reject Ho Step 3: Reject HA Step 3: Fail to Reject Ho Step 3: Fail to Reject HA Step 4: supports Step 4: does not support Step 4: different
Step 4: different Step 4: lower Step Step 4: higher Step 4: 2252 Step 4: 2337
