The target dimension for this part is: 3.701 . So most of the parts will cluster normally around 3.701 inches in length. At the time when the parts were being manufactured, Engineering had determined that a tolerance of ± 0.037 would be acceptable. i. e. the part would work well if it measured somewhere between 3.664 inches and 3.738 inches. Anything beyond the 3.738 in. would cause "sticking problems". Assuming that each cavity produces the same number of parts, estimate the percent of all the products (parts from all cavities) that could be sticking.
