ts with Applications 3.3 HW Question 3, 3.3.31 HW Score: 23.2%, 1.16 of 5 points Save Part 1 of 4 O Points: 0 of 1 Researchers used data on the average reading and math scores on a national test for each state in a nation to develop a regression equation. The rearchers let the V explanatory variable x be the average reading score and the response variable y be the average math score. The regression equation is y = 18.6 + 0.955x and the r-squared value is 0.986. a. One state had an average reading score of 506. Use the regression equation to predict the average math score for this state. b. This state had an average math score of 512. Calculate the residual associated with this state and comment on its value in the context of the problem. c. Does it appear that a state's average reading score is a reliable predictor of its average math score? a. The predicted average math score for this state is (Round to one decimal place as needed.)
