A reporter reported that the average screen time of teens is 6.77 hours per week. You gathered 30 independent samples from your section and obtained an average screen time of 7.8 hours per week, with a sample standard deviation of 2.9 hours. At alpha = 0.10, is this enough evidence to say that the average screen time of your class is higher than the reported screen time? 1. Find the mean value for the null hypothesis 2. Find the critical value 3. Accept or Reject the Null Hypothesis?
