Five members of the football team and five members of the track team ran the 100-meter dash. their times are listed in the table below: football track 12.5 12.4 13.4 11.6 12.2 11.5 11.5 12.4 14.1 13.5 what is the difference of the means for the two groups?

0.46

Step-by-step explanation:

To find the mean, we add together all of the data points and divide by the number of data points.

For the football team, we add

12.5+13.4+12.2+11.5+14.1 = 61.4

Divide this by 5, the number of data points:

61.4/5 = 12.28

For the track team, we add

12.4+11.6+11.5+12.4+13.5 = 63.7

Divide this by 5, the number of data points:

63.7/5 = 12.74

The difference in means is

12.74-12.28 = 0.46

answer: you need to organize this better it does not make sense.
