# Question: Consider the following data for two variables x and y a

Consider the following data for two variables, x and y.

a. Does there appear to be a linear relationship between x and y? Explain.

b. Develop the estimated regression equation relating x and y.

c. Plot the standardized residuals versus for the estimated regression equation developed in part (b). Do the model assumptions appear to be satisfied? Explain.

d. Perform a logarithmic transformation on the dependent variable y. Develop an estimated regression equation using the transformed dependent variable. Do the model assumptions appear to be satisfied by using the transformed dependent variable? Does a reciprocal transformation work better in this case? Explain.
