Trying to understand how to solve this:

In a regression model, with Human Resources data to measure job score performances of workers (Y) based on their scores on a test (X), following a trial period. With a sample of 22 workers, these were the estimates:

Sum of Xi= 2193

SSxx=1820.773

b0=-85.6617

b1=1.75812

MSE=59.16687

What is the 95% predicted upper limit of test score for an employee who received a test score of 99.64 out of 150, after the trial period?
