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). N Summary Statistics Variable X Y 28 28 Mean Variance Corrected SS (SSxx) 7.14 3.978836 107.4286 16.3571429 12.83069 346.4286 Parameter Estimates Variable Parameter Standard Estimates Error Intercept 28.55319 0.80791 Training (X) -1.70745 0.10908 Standard Error 1.13059 R-Square 0.9041 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?
