Question

A drug tester claims that a drug cures a rare skin disease

73%

of the time. The claim is checked by testing the drug on

100

patients. If at least

patients are cured, the claim will be accepted.

Find the probability that the claim will be rejected assuming that the manufacturer's claim is true. Use the normal distribution to approximate the binomial distribution if possible.
