Seventy percent of the students applying to a university are accepted. what is the probability that among the next 18 applicants.
Compute the standard deviation.
Please, use 4 decimal places for the answer.
The formula for the mean of a binomial distribution is: sqrt( n · p · q )
For this problem: n = 18 p = 0.70 q = 1.00 - 0.70 = 0.30
Stamdard Deviation = sqrt( 18 · 0.70 · 0.30 ) = (calculator time)
