11.17 Henderson Corporation makes metal sheets, among other products. When the properly, 92% of the sheets contain no defects, 5% have one defect that is used to make metal sheets works process each, and 3% have two or more defects each. The quality control inspec- tors at the company take samples of metal sheets quite often and check them for defects. If the distribution of defects for a sample is signifi cantly different from the above-mentioned percentage distribution, the process is stopped and adjusted. A recent sample of 300 sheets produced the frequency distribution of defects listed in the following table Number of defects One None Two or More Number of metal sheets 262 24 14 Does the evidence from this sample suggest that the process needs an adjustment? Use a = .01
