I think D would be the correct answer!

Answer 2

[See Below]

Explanation:

_____________________________________________

✦ Mean Absolute Deviation (MAD): The average length between all the data and the mean.

_____________________________________________

✦ First solve for the mean of the data:

✧ Add together all the values:

• 
  `24.50+19.25+28.35+22.50+15.50=110.1`

✧ Now divide by how many numbers or data you have:

• 
  `110.1` ÷
  `5=22.02`

_____________________________________________

✦ Now we solve for MAD:

• 
  `3.716`
