Directions: Answer each of the questions below and show work. Write down the computations you do. Ten FBI agents get together and compare their annual salaries. They are $45,000, $48,000, $49,000, $55,000, $63,000, $64,000, $65,000, $70,000, $75,000, $120,000. A. Compute the mean and median salaries. Be sure to show your work, and answer with a sentence. B. A data point that is very different from other data points is called an outlier. Which of these data points could be considered an outlier? What effect will this outlier have on the mean? C. Compute the mean again, but this time leave out the outlier. How does this number compare to the number you found in question 1?
