Question

comparing the means of two data sets
robin and evelyn are playing a target game. the object of the game is to get an object as close to the center as possible. each players score is the number of centimeters away from the center. robins mean is 107, and evelyns mean is 138. compare the means. explain what this comparison indicates in the context of the data. who is winning the game? why?

Explanation:

Step1: Compare the means

Robin's mean = 107, Evelyn's mean = 138. Since 107 < 138.

Step2: Interpret in game - context

In the game, a lower score (distance from center) is better. Robin has a lower mean score.

Answer:

Robin is winning the game because Robin's mean score (107) is lower than Evelyn's mean score (138), and in this game, a lower number of centimeters away from the center indicates a better performance.
