(a)

Develop a scatter diagram for these data, treating average distance traveled as the dependent variable.

A scatter diagram has 6 points. The horizontal axis ranges from 0 to 1.8 and is labeled: Distance. The vertical axis ranges from 5 to 35 and is labeled: Number. Moving from left to right, the leftmost point is at approximately (0.48, 30), with the next five points extending downward. The points decrease steeply at first and then level off.

(b)

Does a simple linear regression model appear to be appropriate? Explain.

-No, the scatter diagram suggests that there is a curvilinear relationship.

-No, the scatter diagram suggests that there is no relationship.

-Yes, the scatter diagram suggests that there is a linear relationship.

(c)Develop an estimated regression equation for the data of the form

ŷ = b₀ + b₁x + b₂x²: a second-order model with one predictor variable. (Round your numerical values to four decimal places.)

ŷ = 54.8238 is not correcnt
