Question: A regression analysis between task time (y in seconds) and work experience (x in years) resulted in the following least squares line: y_hat = 120

A regression analysis between task time (y in seconds) and work experience (x in years) resulted in the following least squares line: y_hat = 120 - 2x. This implies that if experience is increased by 1 year, the task time, on average, is expected to: increase by 60 seconds.
