Chapter 5 - Normal Probability Distributions - Review Exercises - Page 286: 13

Answer = 0.4495

To find the answer to this question you have to use the alternative presentation of the standard normal distribution i.e. the 0-to-z table (Appendix A). Look for the value of the area between 0 and 1.64. Because of the normal curve's symmetric property, the area between 0 and 1.64 is the same as the area between 0 and -1.64.
