Question

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

Based on visual inspection of the dot plots, which team appears to have the larger mean weight? (5 points)

a
Not enough information is available to draw a conclusion.

b
Both groups are similar.

c
Team C

d
Team D

Answer 1

1st line graph mean: 132.25 LARGER

2nd line graph mean: 123.125

Answer 2

Team C appears to have the larger mean weight.

Explanation:

After seeing the dot plot of two teams i.e. Team C and Team D the conclusion that can be drawn regarding the larger mean of the team is that:

Team C is expected to have larger mean since the dots are for the higher values of weights and hence will result in higher mean. whereas for team D the dots or frequencies are for smaller weights and hence will result in a less mean as compared to team C.

Hence, Team C appears to have the larger mean weight.
