a) Is there an association between engine size and horsepower? (Consider the four categories for Hp listed in the data file)?
Provide meaningful descriptive statistics about the data such as mean, median, standard deviation, range, quartiles, IQR, fences, outliers, etc. and put this data in a table. Include charts that will best display the data - usually bar graphs, histograms, regression plots, are effective. Make sure your tables and charts are appropriately labeled and clearly discussed in your text.
