You have been hired by a used car dealership in Prince George to perform a statistical analysis on the used cars that were sold from their lot in 2005 and 2008. They have provided you a list of 60 prices of the vehicles that were sold. They have also indicated whether the vehicle was sold in 2005 or 2008.
A) Prepare a histogram from the entire sample of price data. Separate the prices into $4000 intervals with the minimum being $10550 and the maximum being $26550.
B) From the histogram that you have just created, use the cutpoints as original values to code the price data into the following 4 new text groups (beginning with the cheapest group): Low, Middle, Middle-High, and High. Tally the results to determine the number of cars sold in each group. Prepare a Pie Chart (%) that will inform the dealership what percentage of the cars sold fell into each group.
C) Make some comments to explain your graph.
