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?

Solutions

Expert Solution

(C) in part (c) , the probability is 0.063 , this means that There is very less chance that number of patients that have side effects is greater than 54.
