Accepted Solution
A:
Answer:9%Step-by-step explanation:To find the percentage of Team B's mean absolute deviation difference in the means, you have to subtract the two means, 59.32-59.1. After this, divide your answer the the mean absolute deviation of Team B, or you could put it all in the calculator or paper like this: [tex]\frac{59.32-59.1}{2.4}[/tex]You'd then end with the decimal: .0916, which you would multiply by 100 to get about 9%
