The data that follow are from two random samples of 37 college males and 42 college females with respect to their commute times to e.
a. Do the distributions of “commute time” for males and females appear to be similar in distribution? Center? Spread? Discuss your responses.
b. Construct a histogram and find the mean and standard deviation for each set of data.
c. Is it possible that both of the samples were drawn from normal populations? Justify your answer.
d. Is the mean commute time for females statistically greater than the mean commute time for males? Use a = 0.05
e. Is there sufficient evidence to show that the standard deviations of these two samples are statistically different? Use a = 0.05.
