                A test of hypothesis is performed to determine whether the proportion of Montrealers (population 1) who want the decriminalization of marijuana is greater than the proportion of Torontonians (population 2) who want decriminalization of marijuana.  A random sample of 120 Montrealers had 90 who favor while a random sample 150 Torontonians also had 90 who favor.  The level of significance of the test is 1%.  Then the classical action limit for the appropriate test of hypothesis is:

    e)	Suppose your conclusion in part (c) is wrong, i.e., you failed to reject the null hypothesis when the mean gas mileage is actually different for the three types of mufflers.   What type of error would you have made?
