Answer:
A) 0.2
Step-by-step explanation:
From least to greatest, the data points are
6, 6, 6, 7, 7, 7, 8, 8, 8, 9
To find the mean, we find the sum of the data points and divide by the number of data points, 10. The sum of the data points is
6+6+6+7+7+7+8+8+8+9 = 72
Dividing by 10, the mean is 72/10 = 7.2.
The median is the middle number in the set. This is 7.
The difference between the mean and the median is
7.2-7 = 0.2.
