TABLE 10-12 A Quality Control Engineer Is in Charge of the Manufacture

question 190

Short Answer

TABLE 10-12
A quality control engineer is in charge of the manufacture of USB flash drives.Two different processes can be used to manufacture the flash drives.He suspects that the Kohler method produces a greater proportion of defects than the Russell method.He samples 150 of the Kohler and 200 of the Russell flash drives and finds that 27 and 18 of them,respectively,are defective.If Kohler is designated as "Group 1" and Russell is designated as "Group 2," perform the appropriate test at a level of significance of 0.01.
-Referring to Table 10-12,construct a 99% confidence interval estimate of the difference in proportion between the Kohler and Russell flash drives that are defective.
