# Question: Samples of three materials under consideration for the housing of

Samples of three materials under consideration for the housing of machinery on a seagoing vessel are tested by means of a salt-spray test. Any sample that leaks when subject to a power spray is considered to have failed. The following are the test results:

Use a suitable statistical computer program to test at the 0.05 level of significance if the three materials have the same probability of leaking in this test.
