In Studies for medication, 15 percent of patients gired weight as a side effect. Suppose 571 Patients are randomly selected-use the normal approximation to the Linomial to approximate the probability that (9) exactly $7 patients will gain weight as a Side effect. (b) no more than 87 patients will gain weight as a Side effect. CC) at least 99 patients will gain weight as a Side effect. What does this result suggest
