<span>The data for the group that studied are more spread out than the data for the group that did not study.
</span><span>The data for the group that did not study are more clustered around the mean than the data for the group that did study.</span>
Answer:
Following are the solution to these question:
Step-by-step explanation:
The frequency of the data value will be the same in dot plots for the number of dots. The frequency table is following:

A=<1,-3,2> and b=<-1,3,-2>
a-3b=<1,-3,2>-3<-1,3,-2>
a-3b=<1,-3,2>-<3(-1),3(3),3(-2)>
a-3b=<1,-3,2>-<-3,9,-6>
a-3b=<1-(-3),-3-9,2-(-6)>
a-3b=<1+3,-12,2+6>
a-3b=<4,-12,8>
Answer: a-3b=<4,-12,8>
