A shortage of candidates has required school districts to pay higher salaries and offer extras to attract and retain school district superintendents. The following data show the annual base salary ($1000s) for superintendents in 20 districts in the greater Rochester, New York, area (The Rochester Democrat and Chronicle, February 10. 2008). Use classes of 150-159, 160-169, and so on in the following. Show the frequency distribution. Show the percent frequency distribution. Show the cumulative percent frequency distribution. Develop a histogram for the annual base salary. Do the data appear to be skewed? Explain. What percentage of the superintendents make more than $200,000?
