Textbook authors must be careful that the reading level of their book is appropriate for the target audience. Some methods of assessing reading level require estimating the average word length. We've randomly chosen 20 words from a randomly selected page in Intro Stats and counted the number of letters in each word:
5, 5, 2, 11, 3, 5, 6, 8, 5, 4, 7, 2, 9, 4, 8, 10, 4, 7, 6, 9
Suppose that our editor was hoping that the book would have a mean word length of 6.8 letters. Does this sample indicate that the authors failed to meet this goal? With a significance level of 0.05, test an appropriate hypothesis and state your conclusion. (i.e state the appropriate null and alternative hypotheses, calculate the test statistic, conclude and interpret it).
Many parents allow underage children to drink alcohol in limited situations when an adult is present to supervise. The idea is that teens will learn responsible drinking
habits if they first experience alcohol in a controlled environment. Other parents take a strict no-drinking approach. Researchers surveyed a sample of 200 students
aged 14 to 17, about their alcohol use and about alcohol related problems. Using a=0.05, answer the questions
