Use the following set of data:

78, 78, 83, 85, 89, 91, 95, 98

What is the range for the set of data?

A 78
B 98
C 87
D 20

D

Step-by-step explanation:

The range is the difference between the largest and smallest values in the data set.

Here largest = 98 and smallest = 78, thus

range = 98 - 78 = 20 → D

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
