GAQM Exam CLSSGB-001 Topic 1 Question 48 Discussion

Actual exam question for GAQM's CLSSGB-001 exam

Question #: 48
Topic #: 1

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?

AThe probability that they would arrive on time using personal vehicles is much higher than using the metro public transportation system (MPTS)

BThe probability that they would arrive on time using the MPTS is much higher than using their personal vehicles

CThe two probabilities are about the same excepting in one case the consistency is higher than the other

DWe need to compile more data around weekends to incorporate for traffic differences

EWhen Standard Deviation is higher the probability goes down and so the MPTS is worse

Ah, the classic 'normal distribution' question. If only life were that predictable. I bet the exam writer's commute is a nice, bell-shaped curve. Mine? More like a hot mess on wheels.

Wait, so they're trying to figure out the best way to get their employees to work on time? I've got a solution - teleportation. No traffic jams, no delays, just *poof* and you're at the office.

E? Really? That's like saying the more unpredictable your commute, the worse it is. I think the exam writer needs to go back to statistics 101.

I'm going to have to go with D. We need more data, especially on weekends, to get a better understanding of the traffic patterns.

Hmm, I'm not sure. The standard deviation for the public transportation system is much higher, so the consistency is lower. I might go with C.

I think the answer is B. The public transportation system has a lower average commute time, so the probability of arriving on time is higher than using personal vehicles.

That's an interesting point, Sanda. But I still think the MPTS is a better option overall, especially considering the policy of not more than 40 minutes for the daily commute.

I disagree, I believe the answer is A. Even though the standard deviation is lower for personal vehicles, the average commute time is higher. So, it's more likely that employees will arrive on time using their own vehicles.

I think the answer is B. The metro public transportation system seems to have a lower average commute time and a higher standard deviation, so it's more likely that employees will arrive on time using it.
