Answer

Work Step by Step

A quality-control expert wants to determine a cluster sample by choosing 10 of 795 clusters. Using a random number table, determine the numbers of the 10 clusters selected. A random number table can be used to determine random numbers in the sample. In the provided study, it starts at row 8, column 38. The clusters are numbered from 001 to 795 because the data has three digits. In the provided table, drop the numbers that are greater than 795. Therefore, the numbers are 763, 185, 377, 304, 626, 392, 315, 084, 565, and 508.
