Extracted text: 6.1 The Empirical Rule 68-95-99.7 According to National Testing data, college math class testing times are Normally distributed with a mean of 41 minutes and standard deviation 8 minutes. The bell curve below represents the probability distribution for testing times. The scale on the horizontal axis is equal to the standard deviation. Fill in the three indicated boxes. H= 41 8. +. Hint: The middle number represents the mean and the outer values are 2 standard deviations away from the mean.
