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 explanatory variable? 2) If we want strength to increase, what must we do to the temperature? Increase OR Decrease? 3) What should be the value of Temperature if we want Strength at 5,000? 4) What is the value of the standard error? Sample Temperature 1 185 2 183 3 187 Strength 5150 5125 5123
