Question

A student rolls a die 15 times and records the results. This is the first set of data. The same student rolls a different die 15 times and records the results. What is an appropriate conclusion about the shape of the dot plots?

A) The first dot plot is skewed to the right.
B) The second dot plot has more of a "belt-shaped curve than the first dot plots.
C) The first dot plot has a unimodal distribution, and the second dot plot has a uniform distribution.
D) The second dot plot looks to have a trimodal distribution.

Answer 1

The first dot plot is skewed to the right, while the second dot plot has more of a uniform distribution with a 'belt-shaped curve'.

Step-by-step explanation:

The first set of data consists of the results of rolling a die 15 times. The histogram for this data is skewed to the right, indicating that there are more low values. On the other hand, the dot plot for the second set of data, which is the result of rolling a different die 15 times, appears to have more of a "belt-shaped curve" than the first dot plot. This suggests that the second dot plot has a more uniform distribution compared to the first dot plot, which has a unimodal distribution.
