Best ResponseYou've already chosen the best response.0Kim claims that because the mean number of words on each page in the math book is greater than the mean number of words on each page in the poetry book, the math book has more words per page. Based on the data, is this a valid inference? No, because there is a lot of variability in the math book data No, because the mean is larger in the math book Yes, because the mean is larger in the math book Yes, because there is a lot of variability in the math book data
