Solvent cement is used to join PVC joints. Researchers are interested in predicting the amount of time is needed for the joint to set (measured in hours) as it is related to temperature measured in degrees F for 4 to 8-inch diameter pieces. A random sample of PVC joints was taken and a linear regression model was found. Use the following output and the fact that R2 = 0.965 to answer the following questions. 4. Find the Correlation and interpret in the words of the problem. 5. Find the residual for a temperature of 60 F, if the time to set was 5.6 hours. 6. Find the residual for a temperature of 50 F, if the time to set was 5.4 hours.
