Question

A punter for a football team is determining the optimal launch angle for kicking a football. Based on a regression equation for this relationship, is a linear model appropriate for using launch angle to predict height?

A) A linear model is appropriate because the residual plot is curved.
B) A linear model is appropriate because many 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.

Answer 1

A linear model is not appropriate because the residual plot shows a clear pattern. So, the correct answer is option c.

Step-by-step explanation:

In determining whether a linear model is appropriate for using launch angle to predict height, we need to consider the residual plot. A linear model is not appropriate because the residual plot shows a clear pattern indicates that a linear model is not appropriate. A residual plot with a clear pattern suggests that a curve would be a better fit for the data. Therefore, option C is the correct choice. So, the correct answer is option c.
