Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify t

he null and alternative​ hypotheses, test​ statistic, critical​ value(s), and state the final conclusion that addresses the original claim. A simple random sample of pages from a dictionary is obtained. Listed below are the numbers of words defined on those pages. Given that this dictionary has 1459 pages with defined​ words, the claim that there are more than​ 70,000 defined words is the same as the claim that the mean number of defined words on a page is greater than 48.0. Use a 0.01 level significance level to test this claim. What does the result suggest about the claim that there are more than​ 70,000 defined words in the​ dictionary?
