Three randomly selected diets are tested to observe Protein content in cow's milk. Data are shown in table: diet 1 2 3 Protein content of cow's milk. 3.63 3.24 3.98 3.66 4.34 4.36 4.17 4.4 3.4 3.75 4.2 4.02 4.02 3.9 3.81 3.62 3.66 4.44 4.23 3.82 3.53 4.47 3.93 3.27 3.3 3.38 3.8 3.8 4.59 4.07 4.32 3.56 3.67 4.15 3.51 4.2 4.12 3.52 4.08 4.02 3.18 4.11 3.27 3.27 3.97 3.31 4.12 3.92 3.78 4 3.69 4.2 4.2 3.13 3.73 4.32 3.04 3.84 3.98 4.18 4.2 4.1 3.25 3.34 3.5 4.13 3.21 3.9 3.5 4.1 2.69 4.3 4.06 3.88 4 If you know that the total sum of squares is 11.84 and diets sum of squares is 0.144. Test if the different diets significantly affect Protein content of cow's milk. Estimate the variance in Protein content. (Use = 0.05)
