He has already earned $8 5 times, so we know that he has 8×5=$40. 88-40=48, so he needs $48 more. 48÷8=6, so he needs to walk the neighbour's dog 6 more times to earn that extra $48

Find the mean:

6 + 6 +10 + 8 + 10 +8 = 48

48 / 6 = 8

The mean is 8.

Now for each number, subtract the mean and square the result:

6 -8 = -2, -2^2 = 4

6 – 8 = -2, -2^2 = 4

10 – 8 = 2, 2^2 = 4

8 – 8 = 0, 0^2 = 0

10 – 8 = 2, 2^2 = 4

8 – 8 = 0, 0^2 = 0

Now find the mean of those results:

4 + 4 +4 +0 +4 + 0 = 16

16 / 6 = 2.6666

Now find the square root:

SQRT(2.666) = 1.63

The answer is A.
