For the data above, perform the following: a. Estimate 5th order polynomial coefficients. b. Compute the coefficient of determination, R?. c. Compute the standard error on all regression coefficients. d. Check the hypothesis if any of the coefficients can be zero at a =0.01. e. Find the mean response and standard error on mean response at x = 210.е. f. Find the 99% confidence interval on the mean response at x = 210. Find the future observation on response at x = 185. h. Find the 99% prediction interval on response at x = 185.
