Baseball regression line prediction: Suppose the equation for the regression line for the number of runs scored in a season, y, is given by y = – 750 + 5400x, where a is the team's batting average. For a team with a batting average of 0.235, find the expected number of runs scored in a season. Round your answer to the nearest whole number.
