To find the sample mean of ball 2 and ball 4, we first need to calculate the total weight of balls 2 and 4.
Weight of ball 2 = 7
Weight of ball 4 = 9
Total weight = 7 + 9 = 16
Now, to find the sample mean, we divide the total weight by the number of balls (2 in this case):
Sample mean = Total weight / Number of balls
Sample mean = 16 / 2
Sample mean = 8
Therefore, the sample mean of ball 2 and ball 4 is 8.
