To find the average number of defects per unit for this process, we need to add up the number of defects for all 10 samples and then divide by the total number of units (in this case, 10 since we have one unit per sample).

Adding up the number of defects gives us:

16 + 12 + 23 + 7 + 14 + 18 + 9 + 15 + 17 + 21 = 152

To get the average, we divide 152 by 10:

152/10 = 15.2

Rounded to the nearest whole number, the average number of defects per unit for this process is 16. Therefore, the best choice is C) 16.
