left Skewed 6. Create the interval of one standard deviation about the mean, that is: - Sx, * +Sx 7. Find out what percent of the data falls within the interval in part 6. (That is number of data values in the above interval divided by total number of data values in your sample.) Give a fraction as well as a decimal or percent value. 8. Create the interval of two standard deviation about the mean. X- 2•Sx, X + 2•Sx 9. Compute the percent of the data that falls in the interval from part 8. Give a fraction as well as a decimal or percent value. 10. Find out exactly what percent of the data supposed to fall within one standard deviation of the mean, assuming a normal distribution for this variable? google it...) 1. How about two standard deviations? 2. How about three standard deviations?
