In studies for a medication, 8 percent of patients gained weight as a side effect. Suppose 549 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 44 patients will gain weight as a side effect. (b) no more than 44 patients will gain weight as a side effect. (c) at least 55 patients will gain weight as a side effect. What does this result suggest? (a) P(44) = (Round to four decimal places as needed) (b) P(X ≤ 44)= (Round to four decimal places as needed) (c) P(X2 55) = (Round to four decimal places as needed) Since 55 is than 8% of the patients, this suggests that the proportion of patients that gain weight as a side effect is 0.08.
