Record the equation (using the variables x and y) of the curve of best fit and the coefficient of determination, r. b) Using Excel, [do not use online version] create a scatter plot of this data set. Perform a exponential regression. Record the equation (using the variables x and y) of the curve of best fit and the coefficient of determination, r. c) Complete (explain) how well these two models fit the data. d) Use both models to predict the membership population of the organization 9 years prior to when the measurements were recorded in the table above. Show all mathematical calculations. e) Upload an excel file containing both scatter plots showing the curve of best fit and their corresponding equations
