Question: In Hamilton County Ohio the mean number of days needed

In Hamilton County, Ohio, the mean number of days needed to sell a house is 86 days (Cincinnati Multiple Listing Service, April, 2012). Data for the sale of 40 houses in a nearby county showed a sample mean of 80 days with a sample standard deviation of 20 days. Conduct a hypothesis test to determine whether the mean number of days until a house is sold in nearby counties is different than the Hamilton County mean of 86 days. Use α = .05 for the level of significance, and state your conclusion.
