Exercise 2.34

The Survey of Earned Doctorates provides data on the length of time in years that it takes to complete a doctorate. Each data point is the mean time for one university. Below is a modified list of this completion-time data, truncated to whole numbers and shortened to make your analysis easier. These data have been collected every 5 years since 1982.
