Question

Refer to the previous exercise.
a. Use the Mean Versus Median applet to investigate what effect adding the outlier of 90 to the data set has on the mean and median.
b. Now add 10 more data values that are near the mean of 2 for the original 10 observations. Does the outlier of 90 still have such a strong effect on the mean?
