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. 7. Find and interpret a 95% confidence interval for the true slope. 8. The researchers find the predicted value for a temperature of 200 F is -3.507 hours. What is the most likely reason for this nonsensical answer?
