Magdeline wants to know if the number of words on a page in her computer 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 and 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 computer science book is greater than the mean number of words on each page in the math book, the computer science book has more words per page. Based on the data, is this a valid inference? Yes, because there is a lot of

Based on the data, is this a valid inference? Yes, because there is a lot of variability in the computer science book data Yes, because the mean is larger in the computer science book No, because the mean is larger in the computer science book No, because there is a lot of variability in the computer science book data

    okay, we know that the bigger the mean absolute deviation there is, the more variability there is, which is not good
