b. Find the mean of the distribution.

c. Find the standard deviation of the distribution.

d. Make a new distribution consisting of the same first four numbers, but change the 8 to 800. Find the mean, median, and standard deviation.

e. Look at your answers to part d. Which statistic was least changed by the outlier of 800?
