Eliminate it to 0.0 minutes? That seems unrealistic!

Wait, how can the metro average be 34 minutes with a 21-minute SD?

I think 40 minutes is a bit too lenient, honestly.

That's interesting, 39 minutes is pretty standard for a commute.

I’m confused about how to approach this. I thought we were supposed to aim for a standard deviation lower than the average commute time, but I can’t recall the exact method.

I feel like the answer should be something reasonable, but eliminating it completely seems unrealistic. Maybe 3.5 minutes?

This question reminds me of a practice problem where we had to find the optimal standard deviation for a different scenario. I think it was about 6 minutes?

I remember something about reducing variation to improve reliability, but I'm not sure how to calculate that here.

I'm not sure about this one. The standard deviations seem important, but I'm not sure how to use them to solve the problem. I'll have to think it through carefully.

Hmm, I'm a bit confused by all the numbers and statistics in this problem. I'll need to re-read it carefully to make sure I understand what's being asked.

This question looks tricky, but I think I can work through it step-by-step. I'll need to compare the commute times and standard deviations to figure out how to reduce the variation.

Okay, I've got this. The key is to reduce the variation in commute time for the employees using personal vehicles to meet the 40-minute policy. I think option C is the right answer.

I remember something about reusing keys, but I thought it was discouraged due to risks. This feels tricky!

Maybe the manager should just install a teleportation system and eliminate the commute altogether. Then they could all show up to work on time, every time!

Ah, the old 'reduce the variation' trick. If I had a nickel for every time I've seen that on an exam, I could probably afford a faster commute!

Hmm, 3.5 minutes? That's a pretty tight window. I hope the employees don't have to be on time down to the second or they'll be in trouble!

I'm not sure why they're asking about reducing variation when the metro system already has a shorter average commute time. Seems like a trick question to me.

The correct answer is C) 3.5 minutes. The goal is to reduce the variation to meet the 40-minute policy, and the standard deviation of 3.5 minutes would do that.
