The Excel file Auto Survey contains a sample of data about vehicles owned,

whether they are purchased new or used, and other types of data. Use the

Descriptive Statistics tool to summarize the numerical data, find the correlations

among each of the numerical variables, and construct PivotTables to find the

average miles/gallon for each type of vehicle and also the average miles/gallon and

average age for each type of new and used vehicle. Summarize the observations that

you can make from these results.
