1. Paper towel advertisements brag on how strong their paper towels are when they are wet. We want to test to see if the leading 4 brands of paper towels have equal average strength. So, we took a section of a paper towel, anchored the edges, and poured 1/4 cup of water in the middle. Then, we slowly added one ounce weights until the paper towel broke. We repeated that several times for the 4 different brands of paper towels. The table below shows the resulting number of ounces required to break the wet paper towels. We tested 6 sheets from each of the four brands. The sample mean and sample variance for each sample is given in the table. Perform a complete 5-step hypothesis test to determine if all of the brands have equal strength. Be sure to include an ANOVA Table. Use a level of significance of 5%.
