Suppose the variance of house selling prices in both Calgary and Edmonton are known. We are interested in knowing if it is likely that mean house selling prices in these two cities differ. Based on a random sample of 40 recently-sold houses from each city, we compute the value of the test statistic to be 2.12. What is the p-value for this test? Express the p-value in DECIMAL format (not as a %). Do not include a zero in front of the decimal.
