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= 59.1 words, s= 15.4 words. Given that this dictionary has 1446 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 48.4 words. Use a 0.10 significance level to test the claim that the mean number of words per page is greater than 48.4 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? O A. Ho: >48.4 words H:u<48.4 words OB. Ho: u= 48.4 words H:u> 48.4 words OC. Họ: H=48.4 words H:u<48.4 words OD. Ho: u= 48.4 words H:u48.4 words Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. |(Round to three decimal places as needed.) State the final conclusion that addresses the original claim. V Ho. There is V evidence to support the claim that there 70,000 defined words in the dictionary.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
