Refer to the Lincolnville School District bus data, which report information on the school district's bus fleet. A copy of the data and a description of the variables appears in Appendix A.2.

The state transportation official requests a monthly report on bus origin, age, maintenance costs and other characteristics. Kindly prepare report and be sure to answer the following questions after you discuss the descriptive statistics for all numerical and categorical variables:

A)A study of school bus fleets reports that the average per bus maintenance cost is 4,000$ per year. Using the maintenance cost variable, conduct a hypothesis test to determine whether the mean maintenance cost for Lincolnville's bus fleet is more than 4,000$ at the 0.05 significance level. Determine the p-value and report the results.
