Response: prognostic index for long-term recovery (Y)

1. What equation will best fit the data based on the shape ofthescatterplot? Exponential? Linear?
2. Using Minitab: Calculate the parameter(s) of the equation that you determined above would be the best fit for the databased on the scatter plot and produce a fitted line plot of the regression equation and the scatterplot ofthe data.Hint: you may need to adjust your starting parameters in Minitab if you do not haveconvergence.
3. Produce a histogram of the residuals.Do they display approximate normality?
4. Based on the above assessments, is the regression equation you determined appropriate for the dataset?
