The architectural firm conducts a hypothesis test to determine whether μ, the mean age of structures located within a 100-mile radius of Wilmington, is greater than 65 years. The test is conducted at α = 0.01 level of significance using a random sample of n = 169 houses and barns located in the specified area. The population standard deviation of the age of structures is assumed to be known with a value of σ = 22.1 years. The firm will open a Vermont branch only if it rejects the null hypothesis that the mean age of structures in the specified area is less than or equal to 65 years.
