Assume Z has a standard normal distribution. Use Appendix Table III to determine the value for z that solves each of the following: (a) P(-z < Z < z) = 0.95. z = i (Round the answer to 2 decimal places.) (b) P(-z < Z < z) = 0.99. Z = i (Round the answer to 2 decimal places.) (c) P(-z < Z < z) = 0.66. (Round the answer to 2 decimal places.)
