To calculate the average number of doctor visits made by the patients, we can use the following formula:
Average = (0*6 + 1*3 + 2*8 + 3*1 + 4*9 + 5*4 + 6*7) / (6+3+8+1+9+4+7)
Average = (0 + 3 + 16 + 3 + 36 + 20 + 42) / 38
Average = 120 / 38
Average ≈ 3.16
Therefore, the average number of doctor visits made by the patients last year was approximately 3.16.
