Each person in random samples of 227 male and 253 female working adults living in a certain town in Canada was asked how long, in minutes, his or her typical daily commute was. (Use a statistical computer package to calculate the P-value. Use μmales − μfemales. Round your test statistic to two decimal places, your df to the nearest whole number and your P-value to three decimal places.)
