According to a research study,American teenagers watched 14.1 hours of television per week last year, on average. A random sample of 11 American teenagers was surveyed and the mean amount of time per week each teenager watched television was 13.3. This data has a sample standard deviation of 1.5. (Assume that the scores are normally distributed.) Researchers conduct a one-mean hypothesis test at the 1% significance level, to test if the mean amount of time American teenagers watch television per week is different than the mean amount of time last year? (a) Ho : μ-14.1: Ha : μ (b) to-1.77 (C) +10005 3.169 14.1, which is a two-tailed test. (d) Which of the following are appropriate conclusions for this hypothesis test? Select all that apply.
