Construct a table.You may give a range for the P-value.Can you conclude that the yield strength of CP titanium welds varies with the cooling rate?

The yield strength of CP titanium welds was measured for welds cooled at rates of $$10^{\circ}C/s,15^{\circ}C/s\ \text{and}\ 28^{\circ}C/s$$. The results are presented in the following table. (Based on the article “Advances in Oxygen Equivalence Equations for Predicting the Properties of Titanium Welds,” D. Harwig, W. Ittiwattana, and H. Castner, The Welding Journal, 2001:126s-136s.)

$$\begin{array}{} \hline \text{Cooling Rate}&\text{Yield Strenghts}\\ \hline 10&71.00&75.00&79.67&81.00&75.50&72.50&73.50&78.50\\ 15&63.00&68.00&73.00&76.00&79.67&81.00\\ 28&68.65&73.70&78.40&84.40&91.20&87.15&77.20&80.70&84.85&88\\ \hline \end{array}$$
a. Construct an ANOVA table. You may give a range for the P-value. b. Can you conclude that the yield strength of CP titanium welds varies with the cooling rate?
