Using your calculator, construct a histogram for each data set that is centered at the mean and has a class width matching the data\'s standard deviation. Use these histograms to compete the following table: Based on the percentages above, comment on whether or not you feel each data set was approximately normally distributed.

Solution

Note that if the data is normally distributed, then percentage of data within 1, 2, or 3 standard deviations from the mean must be approximately 68%, 95%, and 99.7%, respectively.

If the percentage values are close to there numbers, then we can say that the data is approximately normally distributed.
