According to the empirical (69-95-99.7) rule, if a random variable has a standard normal distribution, then approximately 95% of all values fall between ‑scores of –2 and 2. Use the standard normal table or software to determine the precise positive value of such that 95% of the area under the standard normal density curve is between − and . If you use software, you may find this list of manuals useful. Give the positive value of precise to two decimal places. =
