C-chart is the best suited for this since it is widely used to determine if the defects or returns are within the control limits or not.

Mean = average = 8 per day

Z=3

UcL = mean + 3[square root of mean] = 8 + 3 (Sq root of 8) = 16.48

LcL = mean - 3[ square foot of mean] = - 0.485

So the returns are within the control limits.
