You decide to interview a random sample of 15 Canadian teenagers. (a) What is the distribution of the number X who used a fee-based website to download music using Normal approximation? (b) Assuming Normal approximation holds in this scenario, what is the probability that at least 12 of the 15 teenagers in your sample used a fee- based website to download music? (c) Using Normal approximation, what is the smallest number m out of n = 15 teenagers such that P(X < m)="" is="" no="" larger="" than="">
