Escription of binomial distribution

Reference no: EM1398220

Comparing Computer Results. Refer to the Minitab display below. The probabilities were obtained by entering the values of n=6 and p = 0.0167. In a clinical test of the drug Lipitor, 16.7% of the subjects treated with 10 mg of atorvastatin experienced headaches (based on data from Parke-Davis). In each case, assume that 6 subjects are randomly selected and treated with 10 mg of atorvastatin, then find the indicated probability.
