g. Assuming the population mean time of listening to radiom=95 minutes, is there sufficient evidence to conclude that the mean time listened to radio on Saturday is less than national average? Formulate the null and the alternative hypothesis and use both critical value and p-value approach to test this hypothesis at 5% level of significance. (no information about the population standard deviation is available in this question).
