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.
Events A and B are mutually exclusive events defined on common sample space. If P (A) 0.5 and P (A or B) = 0.70, determine P (B).
A research analyst regresses the number of calls for service (Y) on the Fahrenheit temperature at 4:00 in the afternoon (X). The regression equation finds: Y = 62 + 2.4 X with an r 2 of .67
