Answer:
Option (D)
Step-by-step explanation:
Mean=
here, observations are
1×1=1
2×2=2
3×3=9
4×1=4
5×1=5
6×2=12
7×3=21
8×1=8
9×1=9
10×0=0
hence, sum of observations =1+4+9+4+5+12+21+8+9+0=73
Number of observations are=1+2+3+1+1+2+3+1+1+0=15
Mean=4.8..
nearest to 5 .
Hence, option (D) is correct.
D
1+2+2+3+3+3+4+5+6+6+7+7+7+8+9=73
73/15≈5
