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. If the Standard Deviation is uncontrollable then the other option to increase the probability of coming in on time via personal vehicles to work could be ____________?

Since the management has set a policy of not more than 40 minutes for their daily one-way commute, and the average weekday commute time for personal vehicles is already 39 minutes, increasing the average time of commute (choice A) would not be helpful in increasing the probability of coming in on time. Changing the route to work (choice B) might not necessarily reduce the commute time and could potentially lead to even longer commute times. Changing the policy at work and requesting for flexible times based on location (choice D) would involve significant changes at the organizational level and may not be feasible for all employees. Therefore, reducing the average commute time to work by departing earlier (choice C) is the best option to increase the probability of coming in on time via personal vehicles.
