According to the empirical (68-95-99.7) rule, if a random variable z has a standard normal distribution, then approximately 95% of all values fall between z-scores of -2 and 2. Use the standard normal table or software to determine the precise positive value of z such that 95% of the area under the standard normal density curve is between -z and z. If you use software, you may find this list of manuals useful. Give the positive value of z precise to two decimal places.
