Using the data, find the mean, median, mode, range, and standard deviation.
2. Using all of your original data, construct a grouped frequency distribution. The grouped frequency distribution needs at least 4 intervals and each interval must have the same range and no overlap. Begin with the interval 40-49.
3. Using the grouped frequency distribution, draw a histogram.
4. Draw a Normal Distribution Curve. Label all components appropriately. Make sure to include up to plus three and minus three standard deviation labels on your curve.
5. Answer. What percentage of the sample population falls above 1 standard deviation. Show all of your work on how you came to your answer. Then come up with one additional question and show your solution in detail. This should be solved and shown as if you were going to present your conclusions at a business meeting.
