Question

assume that a procedure yields in a binomial distribution with n trials and the probability of sucess for one trial is p use the given values of n and p to find the mean u and standard deviation o also use the range rule of thumb to find the minimum usual value u-2o and the maximum usual value u+2o
n=70 p=2o

Answer 1

u=?
o=? (round to one decimal place as needed)
u-2o=? (round to one decimal place as needed)
u+2o=? (round to one decimal place as needed)
