A statewide real estate agency, Farmers Associates, specializes in selling farm property in the state of ND. Their records indicate that the mean selling time of farm property is 90 days. Because of the recent winter snow fall (below average), they believe that the mean selling time is now greater than 90 days. A statewide survey of 30 farms sold recently revealed that the mean selling time was 94 days, with a standard deviation of 22 days. At the 0.10 significance level, has there been an increase in selling time?
