What’s not the rejection criteria for the following problem.  Two bonding agents, A and B, are available for making a laminated beam, scientists claim that both agent A and agent B have the same performance . Out of 50 beams about 40% beams made with Agent A failed a stress test, whereas 35% beams out of 75 made with agent B failed. A.  z < - z

Calculate the test statistics for the following problem.  Two bonding agents, A and B, are available for making a laminated beam. Out of 50 beams about 35% beams made with Agent A failed a stress test, whereas 40% beams out of 75 made with agent B failed.  Scientists claim that the difference between the failing test of these two agents is less than 2%.
