Problem 11Multiple Choice
A small manufacturing company recorded its quarterly profits (in millions of dollars) over the first two years of operation. The data is as follows:

Your task is to analyze this data to identify the best-fitting mathematical model. Create a scatterplot of profit versus quarter number, then apply regression fits for each model and compare their goodness-of-fit using the coefficient of determination ().
