An accounting clerk is responsible for computing the effective number of hours worked daily (regular time (1.5 times overtime) for each of 500 production workers and for recording the number of days absent each week on the time sheet for each worker. These two functions (computing effective daily hours per worker and recording number of days absent each week per worker) are the job characteristics upon which she is judged. The accounting supervisor draws weekly random samples of 50 time sheets to monitor and help improve the clerk's performance. The following chart reflects 30 weeks of analysis. Can the accounting supervisor use this information to help the clerk improve her pe

Explanation / Answer

(a) She can use this data since the wrong information from the data is 200/1500 fraction only

(b)She can consider only correct responses as from the data the fraction of improperly recorded out of complete population is same as the fraction of correct vs incorrect

(c) probabaility that computed will be correct = 1235/1500

(d)probability that it is recorded correctly = 1425/1500

(e)Probability that time sheet is corrected correctly = 1300/1500

incorrectly is 200/1500
