Question

et X be number of patients whose blood pressure is brought under control with

a new drug, in a group of 50 people who are hypertensive. If the probability

of success for his treatment is assumed to be 0.3, and in this experiment 20

people are treated successfully, is this an excessive number for X? We consider

an outcome as excessive if the probability of the random variable taking a value

larger or equal to the current value is less than 0.05. Use normal approximation not binomial.
