Question 14: Big houses: The U.S. Census Bureau reported that the mean area of U.S. homes built in 2018 was 2559 square feet. Assume that a simple random sample of 22 homes built in 2020 had a mean area of 2654 square feet, with a standard deviation of 184 square feet. Assume the population of areas is normally distributed. Can you conclude that the mean area of homes built in 2020 is greater than that of homes built in 2018 ? Use the a=0.01 level of significance. Part 1: (a) Find the P -value. Use the TI-84 calculator and round your answer to at least four decimal places. The P-value is (BLANK) Part 2: (b) What is the decision? A. Reject H0 B. Do Not Reject H0 Part 3: (c) Interpret the result. We ▼(Choose one) enough evidence at the 0.01 level of significance to conclude that the mean area of homes built in 2020▼(Choose one) that of homes built in 2018. Answer Choice: Have Do Not Have Answer Choice: Is greater than Is not equal to
