Calculate the mean for following set of values -
2.2, 4.2, 6.4, 8.3, 10.5

Correct option is A

Given:

​2.2, 4.2, 6.4, 8.3, 10.5  

Formula Used: 

Mean = $$\frac{sum \ of \ observations} { number \ of \ observations}$$  

Mean = $$\frac{2.2+4.2+6.4+8.3+10.5}{5}$$​

= $$\frac{31.6}{5}\\\ \\= 6.32$$​​
