Which two locations have the greatest overlap in their distributions?

Choose exactly two answers that are correct.

Location Mean MAD
Emerald Lake
20.7
3.0
Kennedy Falls
25.6 2.8
Pine Meadows
14.8 2.9
Spruce Grove
19.2 3.1

Answer 2

@peachpi It is more then one answer.

Answer 3

what do you think?

Answer 4

I think one of the answer is A..

Answer 5

Answer 6

You add and subtract the MAD from the mean to find the range.
Mean 20.7 and MAD 3.0 means range is from 17.7 to 23.7 for Emerald Lake.
I'd do the same thing to the other options and then you can compare the ranges.

Answer 7

Actually, you don't need to do that. The MAD's are all pretty close to 3, so just pick the 2 with the closest means.

Answer 8

B and C.

Answer 9

That would be 25.6 and 14.8, a difference of 10.8. Can you find any other pair with a smaller difference. You were on the right track with A

Answer 10

So, one of the answers was A. Okay. So maybe A and D.

Answer 11

That's the smallest difference, so would have the most overlap.

Answer 12

SO it is A and C. Right?

Answer 13

@peachpi
Is it a and c?

Answer 14

no, you were right. A & D

Answer 15

Oh.
