You may need to use the appropriate appendix table or technology to answer this question. Consider a binomial experiment with n = 20 and p = 0.70. (Round your answers to four decimal places.) (a) Compute f(12). f(12) = (b) Compute f(16). f(16) = (c) Compute P(x 2'16). P(x 16) = (d) Compute P(X 15). P(X 15) = (e) Compute E(x). E(x)= (f) Compute Var(x) and a. Var(x) =
