Answer:
Option B.
Step-by-step explanation:
From the graph during first six months average rainfall was
1st month - 2.91 inches
2nd month - 2.60 inches
3rd month - 3.86 inches
4th month - 3.19 inches
5th month - 3.46 inches
6th month - 3.27 inches
Now we have to calculate the mean of these rainfalls during six months
Mean = [tex]\frac{\text{Total rainfall during six months}}{\text{Number of months}}[/tex]
= [tex]\frac{2.91+2.60+3.86+3.19+3.46+3.27}{6}[/tex]
= [tex]\frac{19.29}{6}[/tex]
= 3.215 inches
Therefore, mean of rainfall was 3.215 inches.
Option B is the correct option.
