Introduction
This research paper will be designed to answer a couple questions regarding statistics about the Buena School District school bus data. The questions I will be discussing and answering will be based on maintenance of the school busses. The question prepared is; is it cheaper or more expensive to run Thompson, Bluebird, or Keiser busses? I will also be addressing another question based on other variables by removing the gas types and making it just one gas type instead of two; does gas type have anything to do with the maintenance of the Thompson, Bluebird and Keiser busses when removed from the regression? In order to answer these questions, both regressions and data sets do not contain the 6 passenger busses, being there are only very few and that they might skew the regression. To explain a little about maintenance on busses, a routine oil change can run anywhere between $150-$250. Diesel engines can go 6,000 to 10,000 miles between oil changes depending on idling time and driving time. If you buy a used bus, one of the first major components that may fail you is the turbocharger. Expect to pay $1,700-$2,000 for a replacement. A tire for a bus can easily cost anywhere between $400-$600. This does not include the price of installation. If your bus should break down, you will need a heavy-duty wrecker, and even a short tow across town can cost $300. A tune-up can also run as much as $600. Gas prices in my opinion are also included with maintenance costs being you need to put fuel in the bus to keep it running. Also there is a big hassle because a full size bus will not fit in the local gas stations, you will need to go to a commercial truck stop for fuel. The biggest thing that people might want to consider is a commercial fueling program because you will buy a lot of fuel at one time. A full size coach can hold 250
