Asimple linear regression model was used to describe the relationship between y 5 hardness of molded plastic and x 5 amount of time elapsed since the end of the molding process. summary quantities included n 5 15, ssresid 5 1235.470, and ssto 5 25,321.368.

a. calculate a point estimate of s. on how many de- grees of freedom is the estimate based?

b. what percentage of observed variation in hardness can be explained by the simple linear regression model relationship between hardness and elapsed time?
