Use the p value method to test the hypothesis that the population mean is 25 meters. The population standard deviation is 20 meters. You collect a sample of 16 elements, in which the mean is = 35. Your client needs the confidence level of 84%. (a) Determine the probability of type I error and which tail(s) your test is dealing with. (b) Convert the sample mean to a z score(s). (c) Convert the z score(s) to a p value(s). (d) Draw the density of meters. Mark up the p value, the probability of a type I error, the hypothesis about the population, and the sample mean. Decide whether you can accept or reject the H0 - show what rule you used.
