4th row will result in the greatest mean.
We are asked to find the row with greatest mean from our given rows.
We will use formula , where,
Let us find mean of each row using above formula.
Therefore, mean of 1st row is 2.8.
Therefore, mean of 2nd row is 3.
Therefore, mean of 3rd row is 3.2.
Therefore, mean of 4th row is 4.2.
Since 4th row has the highest mean, therefore, 4th row will result in the greatest mean.
The 4th row
