A scientist studies how fast a ball will fall when dropped from a height. He drops a ball from different heights and measures the time it takes the ball to reach the ground. Below is the scatterplot of times and heights that he finds, along with the regression line. Next to the scatterplot is a plot of the residuals. The correlation between heights and times is about 0.98. The residual for a height of 60 is about 0.10 seconds. What does this mean? O The prediction from the linear model is too small by 0.10 seconds. O It will take 0.10 seconds for a ball to fall 60 meters. O The prediction from the linear model is too big by 0.10 seconds.
