An experiment was carried out to compare electrical resistivity for 7 different low-permeability concrete bridge deck mixtures. There were 23 measurements on concrete cylinders for each mixture; these were obtained 28 days after casting. The entries in the accompanying ANOVA table are based on information in an article. Fill in the remaining entries. (Round your answers to two decimal places.) You can use the Distribution Calculators page in SALT to find critical values and/or p-values to answer parts of this question. Source df Sum of Squares Mean Square f Mixture Error Total 4515.46 23.92 Test appropriate hypotheses at level 0.05. State the appropriate hypotheses. (Let , = the true mean electrical resistivity for the ith mixture.)
