A manufacturer wants to increase the absorption capacity of a sponge. Based on past data, the average sponge could absorb 3.5 ounces. After the redesign, the absorption amounts of a sample of sponges were (in ounces): 3.6Picture 3.8Picture 4.1Picture 3.5Picture 4.0Picture 3.2Picture 3.7Picture 3.2Picture 3.1Picture and 3.4. What is the decision rule at the 0.01 level of significance to test if the new design increased the absorption amount of the sponge?
