Question 4 a) Teens are reported to watch the fewest total hours of television per week of all the demographic groups. The mean television viewing for teens on Sunday is 1 hour 13 minutes. A random sample of twelve local teens indicates a sample mean viewing time on Sunday is 1 hour 25 minutes with sample standard deviation of 20 minutes. Use a=0.01 to determine that the mean television viewing for teens on Sunday is greater than the national viewing time. Answer the following questions. (Note: Change all times to minutes.). i. Identify the claim and state the Ho and H1. ii. Find the critical value. iii. Calculate the test statistic. iv. Make a decision to reject or fail to reject the Ho. v.
