The article "Characterization of Effects of Thermal Property of Aggregate on the Carbon Footprint of Asphalt Industries in China" (A. Jamshidi, K. Kkurumisawa, et al., Journal of Traffic and Transportation Engineering 2017: 118-130) presents the results of measurements of \(\mathrm{CO}_{2}\) emissions produced during the manufacture of asphalt. Three measurements were taken at each of three mixing temperatures. The results are presented in the following table:

a. Construct an ANOVA table. You may give a range for the \(P\)-value.

b. Can you conclude that the mean emissions differ with mixing temperature?
