Basic Computation: Normal Approximation to a Binomial Distribution Suppose we have a binomial experiment with n = 40 trials and probability of success p = 0.85. (a) Is it appropriate to use a normal approximation to this binomial distribu- tion? Why? (b) Compute μ and or of the approximating normal distribution. (c) Use a continuity correction factor to convert the statement r < 30 suc- cesses to a statement about the corresponding normal variable x. (d) Estimate P(r< 30). (e) Interpretation Is it unusual for a binomial experiment with 40 trials and probability of success 0.85 to have fewer than 30 successes? Explain.
