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 μ and standard deviation σ. ​Also, use the range rule of thumb to find the minimum usual value μ−2σ and the maximum usual value μ+2σ. n=70​, p=0.25 Question content area bottom Part 1 μ=enter your response here ​(Do not​ round.)
