1. A company can use two similar products A and B, which are manufactured by two different suppliers, in its manufacturing site. The company needs to compare the two products in terms of maximum load capacity in tons. The supplier of product A strongly supports the claim that his product is superior. It is known that the two standard deviations in load capacity are equal at 4 tons each. An experiment is conducted in which 100 specimens of each product (A and B) arc tested. Consider the following two cases for the test results:

a. Suppose the test results arc as follows:

Supplier of product B claims that the products do not differ in load capacity and the experiment could easily have given x? _A ? x? _B = 2 even if the two population means are equal. Make an argument that supplier of alloy 13 is wrong. (Flint: Do it by computing

Do you think these data strongly support the claim of the supplier of product A?

b. Suppose the test results arc as follows:

Do these results strongly support the claim of the supplier of product A? Use a similar method as in part (a).
