GAQM CLSSGB-001 Exam - 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

Not sure about that, higher SD doesn't always mean worse outcomes.

I think the probabilities are pretty close, but MPTS has more variability.

Wait, 21 minutes SD for MPTS? That seems really inconsistent.

I totally agree, the stats show MPTS is faster!

Personal vehicles take longer on average, so MPTS might be better.

I feel like we might need more data to really understand the impact of weekend traffic, but I don't think that's the main focus here.

This question reminds me of a practice problem where we compared commute times. I think the consistency of the personal vehicles might give them an edge.

I'm not entirely sure, but I think the higher standard deviation for the MPTS could mean more variability in commute times, which might affect punctuality.

I remember we discussed how a lower average commute time usually indicates a higher probability of arriving on time, so I think the MPTS might be better.

Hmm, I'm not sure about incorporating the weekend data. I think I'll just focus on the weekday commute information provided in the question.

This seems straightforward enough. I just need to plug the numbers into the normal distribution formula and see which option has a higher probability of being under 40 minutes.

I'm a bit confused by the standard deviation values. How do I know which one is more consistent? I'll need to think this through step-by-step.

Okay, I think I've got this. The key is to use the normal distribution to calculate the probability of arriving on time for each option and compare them.

Hmm, this looks like a tricky one. I'll need to carefully compare the mean and standard deviation for both commute options to determine the probabilities.

I'm pretty confident on this one. Proof of stake is designed to be more energy-efficient than proof of work, so it's most often used for public blockchains that need to handle high traffic volumes. I'll select D.

Easy one - the sprint must always be finished, no exceptions. That's the whole point of having a sprint in the first place. I'm confident that option C is the correct answer here.

Mtr is the tool that combines traceroute and ping, so that's the answer I'm going with.

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.

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.
