cure probability

3.84    A drug manufacturer claims that a certain drug cures a blood disease, on the average, 80% of the time. To check the claim, government testers use the drug on a sample of 100 individuals and decide to accept the claim if 75 or more are cured.

(a)   What is the probability that the claim will be re- jected when the cure probability is, in fact, 0.8?

(b)   What is the probability that the claim will be ac- cepted by the government when the cure probabil- ity is as low as 0.7?

 

3.85    The serum cholesterol level X in 14-year-old boys has approximately a normal distribution with

 

 

mean 170 and standard deviation  30.

(a)   Find the probability that the serum cholesterol level of a randomly chosen 14-year-old boy exceeds 230.

(b)   In a middle school there are 300 14-year-old boys. Find the probability that at least 8 boys have a serum cholesterol level that exceeds 230.
