When one thinks of the normal distribution, the first thing that comes to mind is the bell curve and grades. While this is one example of a normal curve that is widely recognized, it is not the only one. Explain your normal curve with items such as the mean and standard deviation. What do the areas in the intervals - to + , - 2 to + 2 and - 3 to + 3 represent with regard to areas under the normal curve? With the mean and standard deviation, calculate what the actual intervals are for your normal curve. Include any citations regarding where you obtained the data for your curve. Respond with thoughtful substantive responses to at least two classmates' postings.
