Question: In a certain binomial distribution, π = 0.20 and n = 30. In using the normal approximation,
- What are the mean and standard deviation of the corresponding normal distribution?
- If x = the number of "successes" among the 30 observations, determine the following:
P ( x = 5), P (4 < x < 7), P (1 < x < 5), P ( x > 7).
