More on paying for music downloads. Consider the settings of Exercises 5.52 and 5.54. (a) Using the 75% rate of the Canadian teenagers, what is the smallest number m out of n 15 U.S. teenagers such that P1X m2 is no larger than 0.05? You might consider m or fewer students as evidence that the rate in your sample is lower than the 75% rate of the Canadian teenagers. (b) Now using the 60% rate of the U.S. teenagers and your answer to part (a), what is P1X m2? This represents the chance of obtaining enough evidence given that the rate is 60%. (c) If you were to increase the sample size from n 15 to n 100 and repeat parts (a) and (b), would you expect the probability in (b) to increase or decrease? Explain your answer. 5.
