The numbers of words defined on those pages are found, with the results n = 10, x = 57.8 words, s= 16.4 words. Given that this dictionary has 1455 pages with defined words, the claim that there are more than 70,000 defined words is equivalent to the claim that the mean number of words per page is greater than 48.1 words. Use a 0.01 significance level to test the claim that the mean number of words per page is greater than 48.1 words. What does the result suggest about the claim that there are more than 70,000 defined words?
