In order to explore further the factors needed to estimate performance on the new processing machines, four variables were listed:

      Thirty employees were selected at random. Data were collected for each, and their performances on the new machines were recorded. A few results are:

As age increases by one year, how much does estimated performance on the new machine increase? (Round your answer to 3 decimal places.)
