Two coworkers commute from the same building. They are interested in whether or not there is any variation in the time it takes them to drive to work. They each record their times for 20 commutes. The first worker's times have a variance of 12.2. The second worker's times have a variance of 16.9. The first worker thinks that he is more consistent with his commute times and that his commute time is shorter. Test the claim at the 10% level.

A) What is s1 in this problem? (Round your answer to two decimal places.)

B) What is n? (Enter an exact number as an integer, fraction, or decimal.)

C) What is the F statistic? (Round your answer to two decimal places.)

D) What is the p-value? (Round your answer to four decimal places.)
