Question 15 • DRHS GA-Statistical Reasoning
A punter for a football team is trying to determine the optimal angle for striking the football off his foot—this is called the launch angle. Using video, his coach records a number of punts kicked using different launch angles and the height in feet for each punt. A regression equation for this relationship is .
Answer
A
A linear model is appropriate because the residual plot is curved.B
A linear model is appropriate because many of the residuals are close to zero.C
A linear model is not appropriate because the residual plot shows a clear pattern.D
A linear model is not appropriate because the y-intercept of the regression equation is negative.
