The partial results below are based on a sample of recently
trained workers, to determine if the number of hours of training
time received (X, in hours) has helped in improving the time taken
to troubleshoot a process problem (Y, in minutes).
Given that a worker has received 428.4 minutes of
training, what is the upper end point in a 95% prediction
interval for the time taken to troubleshoot a process
problem?
