09:Pretest 09:Correlation and Regression
11. Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used.only for the
scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or
computer to obtain the regression equation of the model that best fits the data. You may need to fit several models and compare the
values of R2.
Average sunset times are taken for six months across the summer. Giving the months April through September values 1 through 6, find the
regression equation of the best model.
