    1. Do you know the empirical rule for a normal distribution?

    Your course should surely cover the empirical rule if you are expected to answer this type of question.

    The empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean. The empirical rule can be broken down into three parts: 68% of data falls within the first standard deviation from the mean. 95% fall within two standard deviations. 99.7% fall within three standard deviations.

    The following part of the empirical rule applies to your question part 1: 95% of the data points fall within the range plus and minus two standard deviations from the mean. In part 1, what is the value of two standard deviations?
