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 a researcher who randomly samples 48 warehouses that are for sale across Canada and finds that the mean price per square foot is $340.80, with a standard deviation of $13.89. Assume that prices of warehouse area are normally distributed in population. If the researcher uses a 5% level of significance, what statistical conclusion can be reached? Round your answer to 2 decimal places. The value of the test statistic is and we reject the null hypothesis fail to reject the null hypothesis
