The binomial experiment is given with probability of 11.16%


p=0.1116,n=3200,q=1-p=0.8884

The mean is given by:


\mu=np=3200*0.1116=357.12

The standard deviation is given by:


\sigma=√(npq)=√(3200*0.1116*0.8884)=17.812

The mean and standard deviation are calculated, the mean is 357.12 and the standard deviation is 17.812.
