The accompanying data on y = normalized energy (J/m2) and x = intraocular pressure (mmHg) appeared in a scatterplot in the article "Evaluating the Risk of Eye Injuries: Intraocular Pressure During High Speed Projectile Impacts"â ; an estimated regression function was superimposed on the plot.

x 2761 19764 25713 3980 12782 19008 20782 19028 14397 9606 3905 25731
y 1553 14999 32813 1667 8741 16526 26770 16526 9868 6640 1220 30730

(a) Here is Minitab output from fitting the simple linear regression model.
Predictor Coef SE Coef T P Constant â5090 2257 â2.26 0.048 Pressure 1.2912 0.1347 9.59 0.000 S = 3679.36 R-Sq = 90.2% R-Sq(adj) = 89.2%

Does the model appear to specify a useful relationship between the two variables?

A. No, since the R2 is large and the t-test P-value is small, this does not indicate a useful relationship between normalized energy and interocular pressure.
B. Yes, since the R2 is small and the t-test P-value is small, this indicates a useful relationship between normalized energy and interocular pressure.
C. Yes, since the R2 is small and the t-test P-value is large, this indicates a useful relationship between normalized energy and interocular pressure.
D. No, since the R2 is small and the t-test P-value is large, this does not indicate a useful relationship between normalized energy and interocular pressure.
E. Yes, since the R2 is large and the t-test P-value is small, this indicates a useful relationship between normalized energy and interocular pressure.

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
