Consider a binomial random variable x with n = 20 and p = 0.4. Use Table 1 in Appendix I to find the exact values for the binomial probability. (Round your answer to three decimal places.) P(x2 7) = Approximate the probability P(x 2 7) using the normal approximation with the correction for continuity. (Round your answer to four decimal places.) P(XZ 7): Compare your answers. if The answers are not very close since there is more than a 0.01 difference between them. (f The answers are very close since there is less than a 0.01 difference between them
