Question

Assume that a procedure yields a binomial distribution with n=1222n=1222 trials and the probability of success for one trial is p=38%p=38%.

Find the mean for this binomial distribution.
(Round answer to one decimal place.)
μ=μ= 

Find the standard deviation for this distribution.
(Round answer to two decimal places.)
σ=σ= 

Use the range rule of thumb to find the minimum usual value μ–2σ and the maximum usual value μ+2σ.
Enter answer as an interval using square-brackets only with whole numbers.
usual values =
