Standard deviation = 2.40
Step-by-step explanation:
The calculation of mean and standard deviation is shown below:-
= 2.14
So, the mean is 2.14
Now, For computing the standard deviation first we need to find out the variance which is shown below:-
Variance is
After solving the above equation we will get
= 5.78
Now, the standard deviation is
= 2.404163056
or
= 2.40
