Question

The two dot plots below show the heights of some sixth graders and some seventh graders:

Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot for the first mark, there is 1 dot above the second mark, there is 1 dot above the third mark, there is 1 dot above the fourth mark and there are two dots above the sixth mark.

What are you trying to find/calculate

What are those answer choices

Answer 9

Oh yh sorry about that, just ignore that

Answer 10

Ignoring that just leaves us with

The two dot plots below show the heights of some sixth graders and some seventh graders:

and so there's something incomplete

Answer 11

OH

Answer 12

I'm so sorry i forgot a part of the q

Answer 13

The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 1.7. Approximately how many times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders? (Round all values to the tenths place.)

Answer 14

how many times the variability in 6th graders = variability in heights of 7th graders

so x * 6th graders variability = 7th graders variability

and they told us those numbers

x * 1.2 = 1.7

x = 1.7/1.2

so yes, you are indeed correct

Thank you!
