Next the relationship between the recordable injury rate per
200,000 worker-hours (INJ1) and the number of worker-hours
related to rework per 200,000 worker-hours (Q6) was studied.
The resulting R2-value is 0.977 indicating a very strong relationship,
as shown in Fig. 2. Because the p-value is 0.011, the null
hypothesis was rejected. Practically, this is the same conclusion
reached in the previous relationship. Additionally, because of the
same sample size limitations, this inference is suggestive only.
