1. (10pts.) Dictionary Words. Refer to the sample data used in Chapter 7. 2 problem ( Excel file, Chapter 7.2 page). Given that the dictionary has 1459 pages with defined words, the claim that there are more than 70,000 words is the same as the claim that the mean number of defined words on a page is greater than 50.0. Use a 0.01 significance level to test the claim that the mean number of defined words on a page is greater than 50.0. What does the result suggest about the claim that there are more than 70,000 defined words in the dictionary? Will you get the same conclusion if you use 0.05 significance level? Compare the two conclusions and make a statement about the effect of the significance level. Apply the five-step hypothesis testing procedure practiced in class
