A Manufacturer Wants to Increase the Absorption Capacity of a Sponge

question 121

Multiple Choice

A manufacturer wants to increase the absorption capacity of a sponge. Based on past data, the average sponge could absorb 103.5ml. After the redesign, the absorption amounts of a sample of sponges were (in millilitres) : 121.3, 109.2, 97.6, 103.5, 112.4, 115.3, 106.5, 112.4, 118.3, and 115.3. 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?

• A) Do not reject null hypothesis if computed t is less than 2.580
• B) Do not reject null hypothesis if computed t is less than 2.821
• C) Reject null hypothesis if computed z is 1.96 or larger
• D) Reject null hypothesis if computed t is less than 2.764
