Help with finding the mean, variance and standard deviation
Hi, I can't seem to fiqure out how to find the standard deviation of this problem. I don't know how to get it, and where does it come from. The problem is this. n = 76, p =0.8. I know how to get the mean which is to take 76*0.8, then I'm lost. Could one of you smart people help me pleeze.
I need to find the mean, variance and standard deviation of binomial distribution
Hi, the question is put down as this n = 76, p =0.8. I know how to find the mean, but finding the variance needs me to find the answer of the standard deviation. Thant is what is hard for me. thank you
