find the mean, varince, standard deviation of the binomial distribution with the valudes being n
and p
n=126
p=0.31
what is the mean? round to the nearest tenth
what is the varience?
what is the standard deviation?
Solution
mean of binomial distribution = n*p= 126*0.31=39.06 variance= n*p*(1-p)=
39.06*0.69=26.95 standard dev= sqrt(variance)= 5.19
