A teacher recorded how many minutes her students read per day here is the data from the 20 students:
3,5,7,7,8,10,10,10,12,12,12,14,15,14,14,16,18,18,20,20

0-5 mins:
6-10 mins:
11-15 mins:
16-20 mins:
1. Identify the cluster peak in the dot plot (the three highest recurring values in the dataset)
2. How can the teacher find out about how much most of her students read per day.
