Answer:
6
Explanation:
First of all you should know 'x' is called the class variable and 'f' represent frequency.
The formula for finding Mean is given below:
Mean=Overallsum(xf) ÷ Overallsum(f)
Therefore:
Overallsum(xf)= x1*f1+x2*f2+x3*f3+x4*f4+x5*f5
= 2*3+4*2+6*3+10*1+12*2
=6+8+18+10+24
=66
Overallsum(f)= f1+f2+f3+f4+f5
=3+2+3+1+2
=11
Therefore Mean=66÷11=6
