Problems:

Problems 1-3 are based on the Gasoline_Usage worksheet. This data corresponds to the Per Capita gasoline usage for each state in the US during the year 2000.

1. Identify the Five Measure Summary for the data. Provide an interpretation for these results, and also indicate any states that you believe to be Outliers.
2. For the "Gasoline Usage" data, create a Frequency Table and Histogram with 8 bins. Clearly specify your bins and the frequencies (that is, the number of states) that fall into each bin. Make sure to include the graph of the Histogram.
3. Comment on the Center, Shape, and Spread of this data and also indicate whether or not you think the Normal Model is appropriate for describing this data set.

Problems 4-6 are based on the Car_Speeds worksheet. This data corresponds to the speed in miles per hour (mph) of randomly observed cars passing in front of the campus on 19 th Avenue .

1. Compute the sample mean and sample standard deviation for this data.
2. Using the Normal Model and the parameter estimates from (4), determine what the chance is that the speed of a car passing the campus on 19 th Avenue is between 25 and 30 mph.
3. Suppose that the speed limit is 30 mph. Use the Normal Model to estimate the percentage of cars that are going above the speed limit.
