A simple random sample of 35 pages from Merriam-Webster's Collegiate Dictionary is obtained. The numbers of words defined on those pages are found with the following results: the sample size is 35, the sample mean is 53.3 words per page, the sample standard is 15.7 words per page. Given that this dictionary has 1459 page 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 48.0 words. Assume a normally distributed population. Use a 0.05 significance level to test the claim that the mean number of words per page is greater than 48.0 words.
