Daily Driving The average number of miles a person drives per day is 24. A researcher wishes to see if people over age 60 drive less than 24 miles per day. She selects a random sample of 27 drivers over the age of 60 and finds that the mean number of miles driven is 22.2. The population standard deviation is 3.7 miles. At a=0.05, is there sufficient evidence that those drivers over 60 years old drive less than 24 miles per day on average? Assume that the variable is normally distributed. Use the critical value method with tables. Part: 0 / 5 Part 1 of 5 State the hypotheses and identify the claim with the correct hypothesis. Ho: LL = 24 not claim H : H # 24 claim The hypothesis test is a two-tailed test.Find the critical value(s). Round the answer to at least two decimal places. If there is more than one critical value, separate them with commas. Critical value(s): D Compute the test value. Always round 2 score values to at least two decimal places. =El Make the decision. Reject the null hypothesis. Part: 4 / 5 Part 5 of 5 not enough evidence to support the claim enough evidence to support the claim Summari enough evidence to reject the claim not enough evidence to reject the claim There is (Choose one) that drivers over 60 years old drive less than 24 miles per day, on average.Moviegoers The average "moviegoer" sees 8.5 movies a year. A moviegoer is defined as a person who sees at least one movie in a theater in a 12-month period. A random sample of 50 moviegoers from a large university revealed that the average number of movies seen per person was 9.2. The population standard deviation is 3.2 movies. At the 0.10 level of significance, can it be concluded that this represents a difference from the national average? Part: 0 / 5 Part 1 of 5 State the hypotheses and identify the claim with the correct hypothesis. Ho: H = 8.5 not claim H1 : H # 8.5 claim This hypothesis test is a two-tailed test.Find the critical value(s). Round the answer to at least two decimal places. If there is more than one critical value, separate them with commas. Critical value(s): [:1 Compute the Est value. Always round 2 score values to at least two decimal places. 1 Make the decision.
