Chapter 11 Homework Hints 11.5: calculate normal time (NT) 11.6: use NT from 11.5 and allowance factor—job time [AF JOB ] to calculate standard time (ST) 11.7: use the total ST from 11.6 to calculate the number of units. 11.8: use NT from 11.5 and allowance factor—time worked [AF TIME WORKED ] to calculate ST 11.9: use the total ST from 11.8 to calculate the number of units. 11.10: check the book for help in finding “other factors” to choose between the two models calculated above. 11.19: refer to example 11.6 and use table 11-9 for data to calculate the time based on the learning curve. Note that problems 5-10 are worth 5 points; 19 is worth 10 for a total of 40 points for the assignment.
