Please do not solve on excel. Thank you. do it handwritten.

In an experiment to measure the stiffness of a spring, the length of the spring under different loads as measured as follows: X=loads Y: length 3 10 5 12 6 15 9 18 10' 20 12 22 15 27 20 30 22 .32 28 34 I. Find the regression equations appropriate for predicting: a) The length= given the weight on the spring 1)) The weight, given the length of the spring 1]. The standard errors of the estimates Ill Coeicient of determinations
