Traditional medical treatment will cure about 88% of all people who suffer from a certain eye disorder. Suppose a large medical clinic treats 93 people with this disorder using a new state-of-the- art technique.

a. Estimate the probability that fewer than 80 patients will recover.

b. The director of the hospital recommends that all hospitals adopt this new technique since more than 85 patients in the sample have recovered after being treated with the new technique. Confirm/disprove the director’s claim. Show all your work and interpret your results.
