Partition the total sum of squares into the SSR and SSE. c. Calculate the sample coefficient of determination. d. Test the ...Consider the following set of ordered pairs: Assuming that the regression equation is y = 1.679 + 0.584x and the SSE = 3.547, construct a 90% confidence interval for x = 3. Consider the following set of ordered pairs: Assuming that the regression equation is y = 1.886 + 0.977x and that the SSE = 0.7955, test to determine if the slope is not equal to zero using α = 0.05.
