It is common practice in many countries to destroy (shred) refrigerators at the end of their useful lives. In this process material from insulating foam may be released into the atmosphere. The following data on foam density (g/L) for each of three refrigerators produced by three different manufacturers is given: 1. 30.4 29.2 29.8 2. 27.7 27.1 29.9 3. 27.1 24.8 28.9 5.1) Carry out all appropriate calculations and complete the ANOVA table.
