Good afternoon, could someone explain to me how to do this problem by Ducan's test?
13.1 Suppose that in an industrial experiment an engineer is interested in how the mean moisture absorption of concrete varies for 5 different concrete aggregates. The samples are presented in the recorded data. The model that is considered for this situation is the following. 6 observations were taken from each of the populations, with means M1, M2 .... M5, respectively. We want to try:
Ho = M1 = M2 = ... M5
H1: At least two of the means are not the same
