A computer game. A multimedia statistics learning system includes a test ofskill in using the computers mouse. The software displays a circle at a randomlocation on the computer screen. The subject clicks in the circle with the mouseas quickly as possible. A new circle appears as soon as the subject clicks the oldone. Table 5.3 gives data for one subjects trials, 20 with each hand. Distance isthe distance from the cursor location to the center of the new circle, in unitswhose actual size depends on the size of the screen. Time is the time required toclick in the new circle, in milliseconds.18(a) We suspect that time depends on distance. Make a scatterplot of time againstdistance, using separate symbols for each hand.(b) Describe the pattern. How can you tell that the subject is right-handed?(c) Find the regression line of time on distance separately for each hand. Drawthese lines on your plot. Which regression does a better job of predicting timefrom distance? Give numerical measures that describe the success of the tworegressions.
