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. Book Mean Median Mean absolute deviation
English 48.9 52 9.2
History 40.5 44 1.3

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?
