1. Based on the data from an 8-hour work sampling study shown below Running III III III III III M M M IIITT HITTTIIIIIIIII Idle Broken IIIIIIIIIIIIIIIIIIIIIIIIIIIII Out of stock Other THE Rest& Personal time IIIIIIIIIIIIIIIIII Table 1 Worksampling study a)What % of the time is the machine running? b)What % of the time is the machine broken? c)What is the limit of accuracy of this study in respect of running? d)What is 95% confidence interval of the machine running? In sense of Relative and Absolute accuracy -both are asked!!!! e) Management would like to know how many hours of running time they can expect ? State with 95%confidence that the machine will be able to run for .. hours..............hours of a 8 hour day. f) Your manager says that the range in part d) is unacceptably large. She would like to narrow the range down to 5 minute of running time. How many observation should you collect to achieve this? g) The department consists of 6 operators. The duration of the study in Table 1 shown is 8-hours/day. Records for the period of the study indicate that total of 25 parts of unit were completed by the team. Estimate the average time per part? h)What is 95% confidence interval of the average time? 1) Determine the standard time for one part, given that the average performance rating for the operators was observed to be 90%, and the allowance is as % calculated from the table above (which includes only rest&personal % + Broken % + Out of stock%) i)What can be said about the operators performance rating when total of 35 of parts were produced. 1.
