Question

The numbers of hours that 12 students say they typically spend on homework in a week are 2, 0, 10, 8,10, 8, 8, 8, 10, 10, 8, and 8. What is the mean number of hours? What are the outliers in the data set?

Answer 1

Answer:

The mean is 7.5 and the outliers are 0 and 2

Step-by-step explanation:

To find the mean, add all of the numbers together and divide by the amount of numbers.

2 + 0 + 10 + 8 + 10 + 8 + 8 + 8 + 10 + 10 + 8 + 8 = 90

90/12 = 7.5

To see the outliers, look for the numbers far away from the mean.
