Representatives of the Franklin Insurance Company take medical information over the phone from prospective policy applicants prior to a visit to the applicant's place of residence by a registered nurse who takes vital sign measurements. When the phone interview has incorrect or incomplete information, the entire process is unnecessarily delayed and has the potential of causing loss of business. The following data were collected to see how many applications contain errors. Each sample has 300 randomly selected applications.

Sample	Defects	Sample	Defects
1	18	16	13
2	15	17	17
3	18	18	17
4	6	19	21

7	16	22	14
8	19	23	33
