Assume a binomial probability distribution with n=50 and p=0.25.
Assume a binomial probability distribution with n=50 and p=0.25. Compute the following: (Round all z values to 2 decimal places.)

a. The mean and standard deviation of the random variable. (Round your “?” to 4 decimal places and mean to 1 decimal place.)

b. The probability that X is 22 or more. (Use the rounded values found above. Round your answer to 4 decimal places.)

c. The probability that X is 14 or less. (Use the rounded values found above. Round your answer to 4 decimal places.)
