Problem 3 (10 marks) The average male height in a certain country is 170 cm (u, the population mean). It is suspected that the men in a certain city in that country might have a different average height due to environmental factors. The following is a random sample of 9 men from the city: {176.2, 157.9, 160.1, 180.9, 165.1, 167.2, 162.9, 155.7, 166.2} a) Is there enough evidence to reject the null hypothesis at a significance level a = 0.05? Be sure to specify the null hypothesis and the alternate hypothesis. b) What is the p-value? Does it support the null hypothesis?
