Expert Solution

We use Q-Q plot for checking the normality of the given data after rearranging them in ascending order.Which is described as follows:

Where,

Probability of i =(i-0.5)/n

Z-score of i has been calculated using command =NORM.S.INV().

Standardized value of x can be calculated using cell formula =(B2-AVERAGE($B$2:$B$31))/STDEV.S($B$2:$B$31).

The above graphs shows that data given is approximately normal.
