Use the dots for one and two. what is the difference between the ranges
sergij07 [2.7K]

Answer:

a. 20 points

Step-by-step explanation:

Range = Largest given value - Smallest given value.

<u>Identifying the range of test 1</u>

Looking at the dot plot the lowest test grade appears to be 50 while the highest is 90.

So range of test 1 = 90 - 50 = 40

<u>Identifying the range of test 2</u>

Looking at the plot the lowest test grade appears to be 40 while the highest appears to be 100

So range = 100 - 40 = 60

<u>Identifying the differences between the ranges</u>

Test 1 range : 40

Test 2 range : 60

Difference between the two : 60 - 40 = 20 points
