Why/why not? Select 2 athletes from the list. Find the career statistics for each of the athletes you selected. Calculate a Zscore for each athlete. Tell us what statistic you used as the athlete's raw score, what mean you used, and what standard deviation. *Hint*It might be a little tricky to get means/SDs. If I wanted to get a mean & SD to compute a grand slam Zscore for Williams, I would use this to compute them: https://www.statista.com/statistics/280390/female-tennis-players-with-the-most-victories-at-grand-slam-tournaments/ For Lionel Messi I would use career club goals. Then I would calculate the mean & SD goals of the top 10 scorers. This list reports the number of goals for the top 10 scorers: https://www.goal.com/en-us/lists/cristiano-ronaldo-lionel-messi-pele-who-are-the-top-goal-scorers-/ynctx2o9fa371vi1x0dsgr0np I found this list for top 100m times that can be used for Usain Bolt: https://www.worldathletics.org/records/all-time-toplists/sprints/100-metres/outdoor/men/senior Here's one for boxers: https://boxrec.com/en/ratings?r%5Brole%5D=proboxer&r%5Bsex%5D=M&r%5Bdivision%5D=&r%5Bcountry%5D=&r%5Bstance%5D=&r%5Bstatus%5D=&r_go= ****Remember the Zscore formula is: Z = (X-M)/SD
