Q4. A newspaper article claims that on average, University students spend 4 hours a day using their mobile phone. Assume that the time spent using mobile phones is normally distributed with a standard deviation of 0:0.08 hours per day. You collect a random sample of 16 University students, and test the null hypothesis Ho: \"=4 against the alternative H1: \">4 using a 5% significance level. A. In the context of this problem, what would constitute a Type I error? (2 points) B. If the null hypothesis is true, what is the probability that you will reject the null hypothesis? (3 points). C. If the population mean is actually u=4.07, what is the probability that you will fail to reject the null hypothesis? What is the power of this test? (5 points)
