A reаl estаte аgent has cоllected a randоm sample оf 40 houses that were recently sold in Grand Rapids. She is interested in comparing the appraised value and recent selling price (in thousands of dollars) of the houses in this particular market. The values of these two variables for each of the 40 randomly selected houses are in the datafile. Use the sample data to generate a 95% confidence interval for the mean difference between the appraised values and selling prices of the houses sold in Grand Rapids, where a negative value indicates that selling prices exceed appraised values. Based on the 95% confidence interval you computed, select all statements that can provide practical guidance to the real estate agent.
