Question from yvette, a student: a binomial random variable has a mean equal to 200 and standard deviation of 10. find the values of n and p. |
Hi Yvette,
Use your textbook and look up the formulas for the mean and standard deviation of the binomial random variable. Set the mean equal to 200 and the standard deviation equal to 10 and solve these equations for n and p.
