2. (25 points) Medical Device Resin. A researcher wants to determine a model that can be used to predict the 28-day strength of a new medical device resin. The following data represent the 28-day and 7-day strength (in pounds per square inch) of the new resin along with the new resin’s slump. Slump is a measure of the uniformity of the new resin with a higher slump indicating a less uniform mixture.

Medical Device Resin Data - Use for Problem #2a) Develop a mathematical model that can be used to predict 28-day strength. Properly identify all variables in your mathematical model. b) Determine and interpret the coefficient of determination value. What does that mean to you as an engineer specific to the 28-day strength of this new resin?c) Predict the mean 28-day strength of this resin for a slump of 3.5 inches and 7-day strength of 2450 psi.
