Question

PLZZZ HELP!!! WILL MARK BRAINLIEST! Maggie wants to know if the number of words on a page in her 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.
Mean Median Mean Absolute Deviation
Science 49.7 41 8.4
Math 34.5 44 1.9
She claims that because the mean number of words on each page in the science book is greater than the mean number of words on each page in the math book, the science book has more words per page. Based on the data, is this a valid inference? (1 point)

Question 12 options:

1)

Yes, because there is a lot of variability in the science book data

2)

Yes, because the mean is larger in the science book

3)

No, because the mean is larger in the science book

4)

No, because there is a lot of variability in the science book data

Answer 1

Answer:

4) No, because there is a lot of variability in the science book data  

Step-by-step explanation:

Mean absolute deviation is too large for the science book, therefore the mean is not a reliable data to consider.

Since we can't rely on the mean, Maggie's conclusion is not right.
