The HSD (honestly significant difference) value can be calculated using the formula HSD = q*√(MSE/n), where n is the sample size and MSE is the mean square error obtained from ANOVA. From the given information, ANOVA was conducted and the mean square error (MSE) value can be calculated as MSE=11eaab01_abaf_bf5b_acdb_cd6637dbd8a4_TB4035_11/14=0.207. The critical value of q for F1F1F1S1F1F1F10 = 0.05 and 2,10 degrees of freedom is 3.00. Hence, the HSD value can be calculated as HSD = 3.00*√(0.207/3) = 1.037. Therefore, the best choice is C, which is the closest option to 1.037.
