Assume that a procedure yields a binomial distribution with n = 1382 trials and the probability of success for one trial is p = 0.33. Find the mean for this binomial distribution. (Round answer to one decimal place.) μ = Find the standard deviation for this distribution. (Round answer to two decimal places.) σ= Use the range rule of thumb to find the minimum usual value µ-20 and the maximum usual value μ+2o. Enter answer as an interval using square-brackets only with whole numbers. usual values =
