Suppose that in past years the average price per square metre for warehouses in Canada has been $347.46. A national real estate investor wants to determine whether that figure has changed now. The investor hires an analyst who randomly samples 49 warehouses that are for sale across Canada and finds that the mean price per square metre is $340.89, with a standard deviation of $13.89. Assume that prices of warehouse area are normally distributed in the population. If the analyst uses a 5% level of significance, what statistical conclusion can be reached? What are the hypotheses?
