Due to excessive pollution, GREEN Solutions Inc.is considering subsidizing public transportation to work for its employees.According to the 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.Assuming a Normal Distribution for the commute times by either personal or public transportation, which of these is true?
A . The probability that they would arrive on time using personal vehicles is much higher than using the metro public transportation system (MPTS)
B . The probability that they would arrive on time using the MPTS is much higher than using their personal vehicles
C . The two probabilities are about the same excepting in one case the consistency is higher than the other
D . We need to compile more data around weekends to incorporate for traffic differences
E . When Standard Deviation is higher the probability goes down and so the MPTS is worse
Answer: B
