A simple random sample of 20 pages from a dictionary is obtained. The numbers of words defined on those pages are found, with the results n=20, x 54.1 words, s 16.4 words. Given that this dictionary has 1495 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 great than 46.8 words. Use a 0.10 significance level to test the claim that the mean number of words per page is greater than 46.8 words. What does the result suggest about the claim that there are more than 70,000 defined words? Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Assume that the population is normally distributed What are the null and alternative hypotheses? OA H 46.8 words H: 46.8 words OCH-46.8 words H 460 words Determine the test statistic. 1.99 (Round to two decimal places as needed) Determine the P-value 031 (Round to three decimal places as needed.) State the frial conclusion that addresses the original claim a Ho 468 words H: 46.8 words OD Ho 46.8 words H: 46.8 words Reject Ho There is sufficient evidence to support the claim that there are fewer than 70,000 defined words in the dictionary
