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). Summary Statistics Variable X N Mean Variance Corrected SS (SSxx) 25 6.76 4.77 114.56 25 17.18 18.41 441.84 Y Parameter Estimates Parameter Standard Variable Estimate Error Intercept 29.97451 0.69096 Training (X) -1.90747 0.09744 Standard Error 1.04297 R-Square 0.9434 Given that a worker has received 405.6 minutes of training, what is the lower end point in a 90% prediction interval for the time taken to troubleshoot a process problem?
