Refer to the Buena School District bus data. Prepare a report on the maintenance cost for last month. Be sure to answer the following questions in your report.
a. Around what values do the data tend to cluster? Specifically what was the mean main- tenance cost last month? What is the median cost? Is one measure more represen- tative of the typical cost than the others?
b. What is the range of maintenance costs? What is the standard deviation? About 95 percent of the maintenance costs are between what two values?
