Suppose the average size of a new house built in a certain county in 2014 was 2,272 square feet. A random sample of 25 new homes built in this county was selected in 2018. The average square footage was 2,192, 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 he county has changed since 2014? Determine the null and alternative hypotheses. +₁: H Type integers or decimals. Do not round.)
