Answer:

Row 2

Step-by-step explanation:

To find the mean, we add all the numbers and divide by the number of numbers

Row 1:

(6+5+3+0+4)/5 = 18/5 = 3.6

Row 2:

(4+5+3+5+6)/5 = 23/5 = 4.6

Row 3:

(7+1+4+5+3)/5 = 20/5 = 4.0

Row 4:

(4+2+5+6+3)/5 = 20/5 = 4.0

The greatest mean , or the largest mean is 4.6 or Row 2
