Introduction:
Is there a difference between the number of times that males and females have been
drinking and driving over the past thirty days?
The question above is of interest to us in order to determine whi

Motor Gasoline Consumption in the United States for 2007
The dot plot of the data appears to be right skewed since most of the data entries of the motor
gasoline consumption in trillion Btus are on the right side
Part A: The Introduction
The data sets used for this statistical report were derived from the United States energy
consumption estimates in 2007. The data points are in trillion Btus. The energy consumption

Part C: The Conclusion
The natural gas consumption is a little higher than the coal consumption of the United States in
2007 since the natural gas consumption has a larger mean and more data entries within one
standard deviation of the mean. The distribut

For Section II, the statistical data used to compare and contrast is the total consumption of
natural gas versus the total consumption of coal in trillion Btus for the United States in 2007. I
