In studies for a medication, 12 percent of patients gained weight as a side effect. Suppose 632 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 88 patients will gain weight as a side effect. (b) 88 or fewer patients will gain weight as a side effect. (c) 77 or more patients will gain weight as a side effect. (d) between 88 and 100, inclusive, will gain weight as a side effect
