Lara wants to know if the number of words on a page in her English book is generally more than the number of words on a page in her history 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.
Table shown below
Lara claims that because the mean number of words on each page in the English book is greater than the mean number of words on each page in the history book, the English book has more words per page. Based on the data, is this a valid inference?
Yes, because there is a lot of variability in the English book data
Yes, because the mean is larger in the English book
No, because the mean is larger in the English book
No, because there is a lot of variability in the English book data
