Four types of mortars—ordinary cement mortar (OCM). polymer impregnated mortar (PIM), resin mortar (RM), and polymer cement mortar (PCM)—were subjected to a compression test to measure strength (MPa). Three strength observations for each mortar type are given in the article “Polymer Mortar Composite Matrices for Maintenance-Free Highly Durable Ferrocement” (J. of Ferrocement, 1984: 337-345) and are reproduced here. Construct an ANOVA table. Using a .05 significance level, determine whether the data suggests that the true
