Q:

PLEASE HELP!!!!!!!!!!! Kim wants to know if the number of words on a page in her math book is generally more than the number of words on a page in her poetry 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.Book Mean Median Mean absolute deviationMath 49.9 43 10.2Poetry 41.5 42 1.1Kim claims that because the mean number of words on each page in the math book is greater than the mean number of words on each page in the poetry book, the math book has more words per page. Based on the data, is this a valid inference? (5 points)Yes, because the mean is larger in the math bookNo, because the mean is larger in the math bookNo, because there is a lot of variability in the math book dataYes, because there is a lot of variability in the math book dataYOU WILL GET BRAINIEST 

Accepted Solution

A:
It's D, because the mean doesn't matter as much if it's only taken in a small variability. The mean was selected from 25 random pages in the book, that is why it is right.
