Round all calculated answers to 4 decimal places. Talk this way - To investigate the relationship between diversity and performance in the world's top soccer league, the authors of a paper looked at data from the UEFA Champions League, which is one of the elite soccer leagues in the world. Using information about each player on each team, they created a variable called Diversity, which measured how different the languages spoken by the players on the team are. For each team, they also calculated the variable Differential, which represents the number of goals scored minus the number of goals conceded over the course of the Champions League's season. The data below is consistent with the results found by the authors. A sample of 45 teams is selected. The correlation between Diversity and Differential was found to be r = 0.2185. The scatter plot and a summary of the data is given below. Differential -1.0 -0.5 0.0 0.5 Super Elite Soccer League Teams 20 30 40 50 60 70 80 Diversity
