Question

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. ldentify the 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 diction ary 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 0.05 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? 79 43 82 46 46 56 52 43 61 102 Click the icon to view a table of critical t-values.
