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 = <u>19.33</u>

<u>The mean absolute deviation (MAD) is equal to 19.33</u>

<u>Correct answer is C</u>

Can u tell me if my answers are correct here?
MariettaO [177]
By the process of elimination, it is already not the last 2, so it is 50/50 chance to get it correct, but if you know how to add, you can figure out that 1 million per year in 5 years means that it is 12 million + 5 million, which is equal to 17 million and not 14,500,000. This brings it down only to 500,000$ salary increase per year
