By a work sampling study: Observed Data The machine is being used Proportion of manual labour (machine is running and/or (servicing time) T-% machine is random serviced) Allowance Time Proportion of machine time T₂-% Tea time, Personnal time, Electrical shortages, etc.. Number of Observation 2000 597 Total No. of observations No. of units produced in 100 hours duration=-5000 units Observed rating factor = 120% 2597 Total allowances (PDF1 Style) = 23% of normal time Daily working hours-9hr/employee a) What % (p) of the time Machine is being used (machine time+servicing time) roughly? b) What is the absolute error(1) of the percent Machine is being used? (95% CI) c) What is the relative error of the percent Machine is being used? d) What is 95% confidence interval of working %? In sense of Relative and Absolute accuracy -both are asked!!!!- e) What is the actual production time (OT) taken per article (Attention:Be careful the observed time covers the service and machine time per article (OT) f) Calculate the observed manual labor time (means the service time) per article (Hint: Proportion of manual labour (servicing time) Tnw=14) g) Calculate the normal labour time (service time) per unit T you have calculated in f) h) Calculate the machine time per unit T.

Answer rating: 100% (QA)

a To find the proportion of time the machine is being used machine time servicing time we need to divide the number of observations where the machine is being used by the total number of observations ... View the full answer
