Data relating to the number of defectives in the sample over the past 20 days are given above.
The production manager suspects that the variation in quality was due to deputing an inexperienced substitute operator instead of a regular one, on three days during the period. With the use of a fraction defective chart, specifying the upper and lower control Limits or otherwise, determine the days of poor quality which can be traced or assigned to the inexperienced operator. Do the number of such days, match the number of points indicating out of control situations.
