The number of viewers of American Idol has a mean of 29 million with a standard deviation of 10 million. Assume this distribution follows a normal distribution. What is the probability that next week's show will:
(a) Have between 32 and 40 million viewers? (Round z-score computation to 2 decimal places and your final answer to 4 decimal places.)
(b) Have at least 26 million viewers? (Round z-score computation to 2 decimal places and your final answer to 4 decimal places.)
(c) Exceed 54 million viewers? (Round z-score computation to 2 decimal places and your final answer to 4 decimal places.)
