1. A booklet has 12 pages with the following numbers of :

Answer 1

Answer:

C

Step-by-step explanation:

THe mean deviation is the sum of all the differences of the values from the mean and then we divide by the number of values in the data set.

First, lets find the mean (sum of all the numbers divided by number of numbers):

Mean = (271+354+296+301+333+326+285+298+327+316+287+314)/12 = 309

Now, the mean deviation:

|(271-309+(354-309+(296-309+.....(314-309))|/12 = 19.33

The mean absolute deviation (MAD) is equal to 19.33

Correct answer is C
