Suppose a drug is known to have mild side effects in 75% of the people who take it . It is administered to 100 people. Using both the binomial distribution and the normal approximation, you have calculated the probability that more than 70 people will experience mild side effects. Based on your answers to the previous questions, choose all that apply. i. Since our experimental conditions satisfy the requirements for its use, the estimate from the normal approximation is appropriate...
