Answer:
A
Step-by-step explanation:
The set of values given are
x=10,15,18,20,24
N=5 ⇒number of set of values given
Finding the mean
Mean= sum of x/N
(10+15+18+20+24)/5 =17.4
Finding the Deviations from the mean
║x-mean║=7.4, 2.4, 0.6, 2.6, 6.6
Sum of deviations from mean
sum of ║x-mean║= 7.4+2.4+0.6+2.6+6.6=19.6
Finding mean absolute deviation
Mean absolute deviation=sum of deviations from mean/N
mean absolute deviation =19.6/5 =3.92
