Consider the following data set:
20, 22, 31, 37, 39, 40
How would the range be affected if the data point 28 was added to the data set?
The range would decrease by 0.5.
The range would decrease by 3.
The range would increase by 8.
There would be no effect on the range,

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
