Determine all the answers using excel. Last question to the file:d. Determine the precise p-value for this test.

Suppose the average size of a new house built in a certain county in 2014 was 2,273 square feet. A random sample of 25 new homes built in this county was selected in 2018. The average square footage was 2, 191, with a sample standard deviation of 227 square feet. Complete parts a and b. a. Using a = 0.02, does this sample provide enough evidence to conclude that the average house size of a new home in the county has changed since 2014? Determine the null and alternative hypotheses.
