Question 1011405: An experiment was designed to study the performance
of 4 different detergents for cleaning fuel injectors. The
following "cleanness" readings were obtained with
specially designed equipment for 12 tanks of gas
distributed over 3 different models of engines:
X1 E1 E2 E3 Total
D1 45 43 51 139
D2 47 46 52 145
D3 48 50 55 153
D4 42 37 49 128
T 182 176 207 565
Conduct a two way analysis of variance (ANOVA) present the
result on a ANOVA table and test at 0.01 level of significance
whether there are differences in the detergents or in the
engines. Answer by ikleyn(52818) (Show Source):
