Answer:
1st and 3rd options
Step-by-step explanation:
We have been given three scatter plots. We are asked to choose the plots with cluster.
We know that cluster in a dot plot is formed when many data points lie in a small interval.
We can see that graphs represented by 1st option and 3rd option have many data points in a small interval, therefore, 1st and 3rd options are correct choice.
