) The data below shows the times (in seconds) of all finishers in the finals of the men's 100-meter race (track) in the 2012, 2016, and 2020 summer Olympics. (If there are fewer than 8 times, this means some contestants were disqualified, or did not finish the race.) 2012: 9.63, 9.75, 9.79, 9.88, 9.94, 9.98, 11.99 2016: 9.81, 9.89, 9.91, 9.93, 9.94, 9.96, 10.04, 10.06 2020: 9.80, 9.84, 9.89, 9.93, 9.95, 9.98 i. Find the mean and standard deviation of each data set. ii. Is there evidence that during this 8-year period that runners have gotten faster, either individually or as a group? Explain. iii. If you had to predict the winning time for the 2024 Olympics, what would you predict? Why?
