The dot plots below show the weights of the players of two teams:
Team C

120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140
Weight (pounds)
Team D

120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140
Weight (pounds)
Based on visual inspection of the dot plots, which team appears to have the larger
mean weight? (5 points)

1. Not enough information is available to draw a conclusion

2. Both groups are similar

3. Team C

4. Team D

Respuesta :

The value of the mean of team C and team D will be equal. Then the correct option is B.

What is Mean?

The average of a group of numbers is simply defined as the mean. In statistics, the mean is regarded as one of the indicators of central tendency. Arithmetic mean is a term used to describe the average. It's the percentage of the actual number of observations to the sum of the observations.

The dot plots below show the weights of the players of the two teams:

Team C

120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140. Weight (pounds)

Team D

120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140. Weight (pounds)

Then the mean of team C will be

[tex]\mu _c = \dfrac{120 +121 +122 +123 +124 +.....+139 +140}{21}\\\\\mu _c = \dfrac{2730}{21}\\\\\mu _c = 130[/tex]

Then the mean of team D will be

[tex]\mu _d = \dfrac{120 +121 +122 +123 +124 +.....+139 +140}{21}\\\\\mu _d = \dfrac{2730}{21}\\\\\mu _d = 130[/tex]

Then the value of the mean of team C and team D will be equal.
