From a random sample of 16 students, the sample mean numbers of hours they self-study for classes each day was found to be 6 hours. If the population standard deviation is known to be 1.5, answer the following questions. a) Test at 5% significance level that population mean study hours is equal to 5 against it is not equal to 5. Write down the necessary components for this hypothesis test. Draw a figure explaining the test. b) Derive the p-value. Draw the figure. c) If the true population mean was 6.5, calculate Type II error. Draw the figure.
