A study is made of the effect of curing temperature on the compressive strength of a certain type of concrete. Five concrete specimens are cured at each of four temperatures, and the compressive strength of each specimen is measured (in MPa). The results are as follows: Temperature (°C) Strengths 31.2 29.6 30.8 30.0 31.4 10 30.0 27.7 31.1 31.3 30.6 20 35.9 36.8 35.0 34.6 36.5 30 38.3 37.0 37.5 36.1 38.4 Construct an ANOVA table. You may give a range for the P-value. Can you conclude that the mean strength differs with temperature? a. b.
