suppose in an industrial experiment an engineer is interested in how the mean absorption of moisture in concrete varies among 3 different concrete aggregates. The samples are exposed to moisture for 48 hours. it is decided that 6 samples are to be tested for each aggregate, requiring a total of 18 samples to be tested. the data are recorded in the following table. Results of one-way ANOVA show that at least two of the samples are significantly different (F(2,15)=10.96; p-value=0.001165). Perform pairwise comparisons using Tukey's procedure at level significance of 0.05. please hand or typed calculations.
