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 asimple random sample of 17 homes built in 2020 had a mean area of 2592 square feet, with a standard deviation of 179 square feet.Assume the population of areas is normally distributed. Can you conclude that the mean area of homes built in 2020 is not equal to thatof homes built in 2018 ? Use the a=0.01 level of significance.H: µ=2559H: u#2559Part 1 of 3(a) Find the P-value.
