Task 6: Compare Raw Data Distribution to "Standard" Normal Distribution. Using your raw data gathered in Task 2 and the sample mean and sample standard deviation calculated in Task 3, calculate:

-percentage of your raw data falling within one standard deviation of the mean;

-percentage of your raw data falling within two standard deviations of the mean;

-percentage of your raw data falling within three standard deviations of the mean
