A statistician is investigating the effect of two factors, A and B, on growth of a bacteria, at 0.05 significance level. The following information is available from his experiment: SSA = 7.52, SSB - 2.36, SS Error - 6.77. SSTotal - 18.89, Total degrees of freedom = 17, MS - 3.76. MSB - 1.18 Which statement(s) is (are) True? The interaction of the main factors (AB) is not significant. The percentage contribution of Error relative to the Total sum of squares is 35.84. Factor B is not significant. OHO : MA = MA
