Hi,

Looking at this question here.

(

#17 on quiz 7).

To me, the E dot looks halfway between the 0.025 and 0.05. As Greg shows in the video, if we assume it’s 0.03, then we get:

\frac{10,000}{.03} = 330,000
It’s clear to me that the B point is at

(0.5,3.5), so we have a total of 7,000 employees.

330/7 = 47 so we round to 50.

However, if we assume that the point is at 0.035 (also reasonable considering the graphic):

\frac{10,000}{.035} = 286,000

286/7 = 41

So I rounded down to 40.

Am I missing something here? Thank you!

It looks like E = 0.025. The problem you raise is more of a case of the question’s options not spaced properly (i.e, all reasonable interpretations of a point should result in the same answer). @gregmat

Hi, I might be missing something, but I disagree- I don’t think that it looks like 0.025, since the spacing on the x grid is 0.025 (only every other is marked). Therefore the y axis should be at x=0.025. E is halfway between 0.025 and 0.05. Do you agree?

Personally, I think E = 0.025. However, the reason I tagged Greg is that because I think you’ve presented a valid case of the question being ambiguous. A good question shouldn’t have the discussion we’re having here.

In other words, I think we need to change the question to avoid this confusion.

How do you see 0.025? Haha. This make sense if we assume the y-axis is at x=0, but each box has x-width 0.025 (0.05, unlabeled, 0.1) etc. Therefore it seems like E is between 0.025 and 0.05. It’s late though and I could be trippin’.

This has been fixed - the options have been spaced so that all reasonable interpretations of that point should result in the same answer.
