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 u and standard deviation o. Also, use the range rule of thumb to find the minimum usual value u - 20 and the maximum usual value p + 20. n=1528, p =3/4 H= (Do not round.) 6= (Round to one decimal place as needed.) H - 20= (Round to one decimal place as needed.) H + 20= (Round to one decimal place as needed.)
