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 24 24 Mean Variance Corrected SS (SSxx) 7.21 5.824275 133.9583 15.9583333 19.08514 438.9583 Parameter Estimates Variable Parameter Standard Estimate Error Intercept 28.48491 0.81973 Training (X) -1.73779 0.10806 Standard Error 1.25073 R-Square 0.9216 Given that a worker has received 432.6 minutes of training, what is the lower end point in a 98% prediction interval for the time taken to troubleshoot a process problem?
