Question

Maria wants to know if the number of words on a page in her earth science book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
She claims that because the mean number of words on each page in the earth science book is greater than the mean number of words on each page in the math book, the earth science book has more words per page. Based on the data, is this a valid inference?

A.
Yes, because the mean is larger in the earth science book.
B.
No, because the mean is larger in the earth science book.
C.
Yes, because there is a lot of variability in the earth science book data.
D.
No, because there is a lot of variability in the earth science book data.

Answer 1

Answer:

I believe the answer is D

Step-by-step explanation:

I'm not 100% sure though

Answer 2

Step-by-step explanation:

the correct answer is D. No, because there is a lot of variability in the earth science book data.

First of all you need to remember the key word variability which is the distance that all points differ from each other. And remember if the mean absolute deviation is higher the more variability it has but if the mean absolute deviation is lower the lower the variability it is.

So using the process of elimination the answer is d so hopefully that is the correct answer and give brainliest to the first people that answer it first.
