$250$, $251$, $253$, $253$, $253$, $254$, $257$, $257$, $259$, $259$, $261$, $263$, $265$, $270$, $291$ rpm

1. On grid paper, draw a combination histogram and boxplot. Do not use a calculator.

   Hint (a):

   Consider what an appropriate interval size would be for this data set.

2. Describe center, shape, spread, and outliers, similar to the way you did in problem 10-44.

   Hint (b):

   Review the work you did on problem 10-44.

3. When reporting the center of this data, or the “typical rpm,” which would be more appropriate, the mean or the median? Why?

   Answer (c):

   The median ($257$) is probably the more appropriate descriptor of the center.
   This is because the outlier of $291$ has skewed the data some.
   Removing the outlier causes the mean and the median to be nearly the same.
