Kelly wants to know if the number of words on a page in her geometry book is generally more than the number of words on a page in her science 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. kelly 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 geometry book, the science book has more words per page. based on the data, is this a valid inference?
