Baseball regression line prediction: Suppose the regression line for the number of runs scored in a season, y, is given by y=-700+5800x, where I is the team's batting average. a. 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. b. If we can expect the number of runs scored in a season is 500, then what is the assumed team's batting average? Round your answer to three decimal places.
