According to a manager it takes an average weekday commute of 39 minutes with a Standard Deviation of 7 minutes for the employees to get to work while they use their personal vehicles for their office commute while the management set a policy of not more than 40 minutes for their daily one-way commute. A survey conducted one day on 70 employees showed an average of 34 minutes commuting time using the metro public transportation system with a Standard Deviation of 21 minutes.

A. Increase the average time of commute

B. Maintain the average time of commute and change route to work

C. Reduce average commute time to work by departing earlier

D. Change policy at work and request for flexible times based on location
