Problem 8BSC
Finding μ, σ, and Unusual Values. In Exercises, assume that a procedure yields a binomial distribution with n trials and the probability of success for one trial is p. Use the given values of n and p to find the mean μ and standard deviation σ . Also, use the range ruh of thumb to find the minimum usual value μ – 2σ and the maximum usual value μ – 2 σ.
Clinical Trial In a clinical trial of the cholesterol drug Lipitor, 94 subjects were treated with 80 mg of Lipitor, and 6.4% of them developed headaches, so n = 94 and p = 0.064.

ANSWER:Answer:
Step 1 of 1
Given, n = 94 and p = 0.064, q = 1 - p = 0.936
Binomial distribution with n trials and the probability of success for one trial is p.
Using the given values of n and p to find the mean μ and standard deviation σ
