Question 910320: Assume that a procedure yields a binomial distribution with n trials and the probability of success for one trial is p. use the given values of n and p to find the mean and standard deviation. Also use the range rule of thumb to find the minimum usual value and maximum usual value.
n=180, p=0.3

mean = .3%2A180%29 = 54 and sd = sqrt%28.3%2A.7%2A180%29=+sqrt%2837.8%29 = 6.148
54 ± 2(6.148)
minimum usual value 42
maximum usual value 66
