- The computer output below shows the result of a linear regression analysis for predicting the concentration of zinc, in parts per million (ppm), from the concentration of lead, in ppm, found in fish from a certain river. Which of the following statements is a correct interpretation of the value 19.0 in the output? On average there is a predicted increase of 19.0 ppm in concentration of lead for every increase of 1 ppm in concentration of zinc found in the fish. On average there is a predicted increase of 19.0 ppm in concentration of zinc for every increase of 1 ppm in concentration of lead found in the fish. The predicted concentration of zinc is 19.0 ppm in fish with no concentration of lead. The predicted concentration of lead is 19.0 ppm in fish with no concentration of zinc. Approximately 19% of the variability in zinc concentration is predicted by its linear relationship with lead concentration.arrow_forwardExplain why it is not a good idea to exclude an intercept, b0 , from any linear regression model?arrow_forwardA pack of gum at the grocery store is $1.75.
