Conclude the mean.

Public transportation as well as the automobile are two methods an employee can use to get to work each day. Samples of times recorded for every method are shown. Times are in minutes.

 Public Transportations: 28 29 32 37 33 25 29 32 41 34 Automobile: 29 31 33 32 34 30 31 32 35 33

1) Compute the sample mean time to get to work for each method.

2) Compute the sample standard deviation for each method.

3) On the basis of your results from parts (A) and (B) which method of transportation should be preferred? describe.

4) Develop a box plot for each method. Does a comparison of the box plots support your conclusion in part (C)?
