1.A study conducted at VP1&SU to determine if certain static arm strength measures have an influence on the "dynamic lift" characteristics of an individual. Twenty five individuals were subjected to strength tests and then were asked to perform a weight lifting test in which weight was dynamically lifted overhead. The data are given here.
(a) Estimate a and 0 for the linear regression curve μ Y?x = a + 0x.
(b) Find a point estimate of μ y?30.
(c) Plot the residuals versus the Xs (arm strength).Comment.
