3. Outliers: For the “Height in Inches” data, compute a z-score for each record and create a histogram of the transformed data (test different bin widths). What percentage of z-scores lie between -1 and 1? Between -2 and 2? Between -3 and 3? Do the data correspond to the expected features of a “symmetric-mound shaped distribution”?

4. Box-Plot: Create a box-plot for the “Car Mileage” and the “Height in Inches” data on separate graphs. Use Microsoft Excel to compute the essential features of the box-plot (Median, Quartiles, IQR, Outliers). You can create your box plots by hand on a separate sheet of graph paper. Be sure to indicate the key features of a box-plot on your graph, namely, the median, lower and upper quartiles, inner and outer fences and be sure to indicate outliers. Comment on...
