In: Statistics and Probability
Each person in random samples of 227 male and 283 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 down to the nearest whole number, and your P-value to three decimal places.)

Is there enough evidence to show that there is a difference in mean
commute times for male and female working residents of this town?
Use a significance level of 0.05.
