Sample Question: Binomial Probability Distribution
Assume a binomial probability distribution with n=40 and Ï? =.30(pi =.30) . (Round all z values to 2 decimal places.)
Compute the following:
(a) The mean and standard deviation of the random variable. (Round your "Ï?" to 4 decimal places and mean to 1 decimal place.)
?=
Ï?=
(b) The probability that X is 16 or more. (Use the rounded values found above. Round your answer to 4 decimal places.)
