Mile Run Record Times: This table shows that the world record time for the mile run has been decreasing from 1913 through 1985. a. Make a scatter plot of the data. Use the last two digits of the year for x and the number of seconds for y. A window with a range for y of [220, 260] will allow you to view the entire data set on the screen. Plot the bestfitting linear function on the same screen. Sketch the result. for the data. Plot it on the same screen as in part a. Can you see any difference between the exponential and linear graphs? a world record of 223.13 seconds for the mile run. Which function comes closer to predicting this result, the linear or the exponential? e. In 1954, Roger Bannister of Great Britain broke the 4-minute mile. Until that time, it had been thought that 4 minutes (240 seconds) was the quickest a human being could run a mile. What do the data and residual plot suggest happened in the years just before and just after Bannisters feat?
