Answer 1

The 4th row

Hope it Helped

Answer 2

4th row will result in the greatest mean.

Explanation:

We are asked to find the row with greatest mean from our given rows.

We will use formula
`\bar{x}=(\Sigma x)/(n)`, where,

`\bar{x}=\text{Mean}`,

`\Sigma x=\text{Sum of all data values}`,

`n=\text{Number of data points in sample}`

Let us find mean of each row using above formula.

`\text{Mean of row 1}=(4+2+2+3+3)/(5)`

`\text{Mean of row 1}=(14)/(5)`

`\text{Mean of row 1}=2.8`

Therefore, mean of 1st row is 2.8.

`\text{Mean of row 2}=(3+3+4+3+2)/(5)`

`\text{Mean of row 2}=(15)/(5)`

`\text{Mean of row 2}=3`

Therefore, mean of 2nd row is 3.

`\text{Mean of row 3}=(2+4+3+4+3)/(5)`

`\text{Mean of row 3}=(16)/(5)`

`\text{Mean of row 3}=3.2`

Therefore, mean of 3rd row is 3.2.

`\text{Mean of row 4}=(3+4+4+7+3)/(5)`

`\text{Mean of row 4}=(21)/(5)`

`\text{Mean of row 4}=4.2`

Therefore, mean of 4th row is 4.2.

Since 4th row has the highest mean, therefore, 4th row will result in the greatest mean.
