The dot plots below show the scores for a group of students who took two rounds of a quiz: Which of the following inferences can be made using the dot plot?

The range of each round is the same.
There is no overlap between the data.
Round 1 scores were higher than round 2 scores.
Round 2 scores were lower than round 1 scores.

Because the range is the highest number minus the lowest The range of each round is the same.

Step-by-step: Because the range is the highest number minus the smallest number so for round one that would be 8-5 Which is three and for round two 9-6 which is also three.

A) the range of each round is the same

Step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

the answer is a.

135 and 80
