Question

On a piece of paper draw a box to represent the data .then determine which answer choice matches the box plot you drew.

Answer 1

Answer:

The answer is A

Step-by-step explanation:

First I found the average for the whole thing. . .

So add all the numbers; 12 + 14 + 17 + 23 + 25 + 30 + 32 + 37 + 38 + 40 +41 = 309.

Divide 309 to 11 (bc there is 11 numbers in total)

309/11= 28.0909090909 and that will be almost equal to 28, (28 is ur average, and it will be in the middle of the box inside.)

So, eliminate B, C, and D.

You are left with A and B

To find the lower quartile, you need to add 12 all the way to 27; 12+13+14+15+16+17+18+19+20. . . etc . . . and u will get 312.

Divide 312 to 16 (bc u have the total of 16 numbers from 12 to 27) you will get 19.5.

19.5 is closest to 20 so ur lower quartile is 20.
