The following table shows students’ test scores on the first two tests in an introductory physics class.   Physics Test Scores First test, x 7373 6161 6969 4242 8888 8787 4242 4444 4040 4848 6868 6464 Second test, y 7474 6262 6262 4343 7878 6969 3838 4343 3030 4848 6666 5454   Step 1 of 2 :   Find an equation of the least-squares regression line. Round your answer to three decimal places, if necessary.     Step 2 of 2 :  If a sudent scored a 75 on his first paper, make a prediction for his score on the second test. Assume the regression equation is appropriate for prediction. Round your answer to two decimal places, if necessary.
