The testing times for a group of college students were normally distributed with a mean of u = 32 minutes and a standard deviation of o = 2.2 minutes. The bell curve below represents the distribution for testing times. The scale on the horizontal axis is equal to the standard deviation. Fill in the indicated boxes. u-20 H+o H+20 µ H- 30 H-0 Used the Empirical Rule to complete the following statements: 68% of testing times were between minutes and minutes. 95% of testing times were between minutes and minutes. 99.7% of testing times were between minutes and minutes. 50% of testing times were below minutes.
