In studies for a medication, 10
percent of patients gained weight as a side effect. Suppose 447 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that
(a) exactly 45 patients will gain weight as a side effect.
(b) no more than 45 patients will gain weight as a side effect.
(c) at least 54 patients will gain weight as a side effect. What does this result suggest?
