Refer to the asphalt data in Example 1.12.
a. Construct a box plot for the asphalt data.
b. Which values, if any, are outliers?
c. Construct a dot plot for the asphalt data.
d. For purposes of constructing box plots, an outlier is defined to be a point whose distance from the nearest quartile is more than 1.5 IQR. A more general, and less precise, definition is that an outlier is any point that is detached from the bulk of the data. Are there any points in the asphalt data set that are outliers under this more general definition, but not under the box plot definition? If so, which are they?
