Find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p. n=73 p=.7
Find the mean of the binomial distribution
mean=?
--------
mean of a binomial distribution = np
Your Problem:
mean = 73*0.7 = 51.1
variance = npq = 51.1*0.3 = 15.33
Standard Deviation = sqrt(npq) = sqrt(15.33) = 3.915354...
