Answer 3

I'd much rather guide you through finding the solution to this problem yourself.
Would you mind taking that data and arranging it in ascending order?

Answer 4

1,2,4,6,7,8,100

Answer 5

is that it

Answer 6

Lets set the data in increasing order:

Answer 7

@mathmale

Answer 8

1,2,2,4,4,4,6,6,7,7,7,8,8,8,100

Answer 9

wouldnt it be A.

Answer 10

The outlier is 100.
The median is 6

Answer 11

Without 100, the median is still 6

Answer 12

so.. what will be the answer

Larryboxaplenty did the right thing in arranging the data in ascending order.

Now, would YOU please explain how you find the median of a data set after you've arranged the data in ascending order?

If you don't know how to do that, please google "median":.

Answer 14

The maximum is the highest number.
The minimum is the lowest number.
The difference between the max and min is the range.

With 100: range = 100 - 1 = 99
Without 100: range = 8 - 1 = 7

Without the outlier, the range decreases

Answer 15

so D

Answer 16

thank you so much

Answer 17
