A binomial distribution has n=1580 and p=0.798
A Find the mean of this distribution to the nearest tenth.
mean = np
-------------------------
B Find the variance and standard deviation of this distribution to the nearest hundredth
variance = npq
std = sqrt(npq)
-------------------------
C Find the minimum and maximum usual values of U +- 2 r
u - 2r = np-2sqrt(npq)
u + 2r = np+2sqrt(npq)
