(2 points) What is the independent variable in this experiment? 2. (9 points) Show why ANOVA is an appropriate analysis to determine if temperature affects strength. (i.e., do the data meet the assumptions to use ANOVA?) 3. (7 points) Now answer the research question: does temperature affect strength? If yes, describe the relationship (which temperatures produce the highest strength?) Support your answer with both statistical (numerical) evidence and practical interpretation. Be concise: answer the questions directly. 4. (2) If production uses 20 C for curing, what is the 95% range (confidence interval) of where the compressive strength of the next specimen tested will fall?
