9. Refer to the accompanying technology display. The probabilities were obtained by entering the values of n=5 and p=0.793. In a clinical test of a drug, 79.3% of the subjects treated with 10 mg of the drug experienced headaches. In each case, assume that 5 subjects are randomly selected and treated with 10 mg of the drug. Find the probability that at least four of the subjects experience headaches. Is it unusual to have fewer than four subjects experience headaches?

8. In a clinical trial of a drug used to help subjects stop smoking, 818 subjects were treated with 1 mg doses of the drug. That group consisted of 41 subjects who experienced nausea.
