8. (Hypothesis testing using the p-value method, chapter 9) Last year, students used spent on average 144 minutes per day on social media. Suppose we want to test whether or not this is still the case this year. Assume the population of 1,800 students is normally distributed with a standard distribution of 12. We take a sample of 30 students and find that they spend, on average, 147 minutes on social media per day. Formally state the hypothesis and use the p-value method to test the hypothesis at the 90%, 95% and 99% levels.
