Public transportation and the automobile are two methods an employee can use to get to work each day. Samples of travel times recorded for each method are shown. Times are in minutes.
a. Compute the sample mean time to get to work for each method (to the nearest whole number).
b. Compute the sample standard deviation for each method (to decimals).
c. On the basis of your results from parts (a) and (b), which method of transportation should be preferred? Explain.
d. Select a boxplot for each method.
Does a comparison of the boxplots support your conclusion in part (c)?
