Assume that a procedure yields a binomial distribution with n trials and the probability of success for onetrial is p. Use the given values of n and p to find the mean u and standard deviation o. Also, use the rangerule of thumb to find the minimum usual value u- 20 and the maximum usual value u+ 20.In a Gallup poll of 1013 randomly selected adults, 66% said that theyworry about identity theft, so n = 1013 andp = 0.66. Round to 1 decimal.Mean =Standard Deviation =Minimum Usual Value =Maximum Usual Value =
