Question 1055538
In a certain high school, 20% of the graduating seniors chose to attend the Ohio State University for college. If there are 265 seniors in the graduating class, the number who will go to the Ohio State University is a binomial random variable. 
The mean is 53; how would you find the standard deviation? 
----
Ans:: std = sqrt[p*q*n] = sqrt[0.2*0.8*265] = 6.512
