Assume that x is a binomial random variable with n=400 and p=0.30. Use a normal approximation to find p(x>100)
Added by Trevor M.
Step 1
The mean of a binomial distribution is given by μ = np, where n is the number of trials and p is the probability of success. In this case, n = 400 and p = 0.30, so the mean is μ = 400 * 0.30 = 120. The standard deviation of a binomial distribution is given by σ = Show more…
