A materials engineer wants to understand the relationship between the strength of plastic cases and the temperature at which the strength measurements were made. The engineer collects several samples from the manufacturer and records the following observations. Using the data below and what you have learned in Forecasting, determine the following (use four decimal places for values): 1) Which is the response variable? 2) What would be the value of the coefficient of correlation between the two variables? 3) What would be the complete interpretation of the relationship between the two variables (consider sign and value)? 4) What is the value of the standard error for the given data set?
