Problem 1
Magic, Inc. carried out a time study of an existing job to develop new time standards. A worker
was observed for 50 minutes. During that period, 42 units were produced. The analyst rated the
worker as performing at an 85 percent performance rate. Allowances in the firm for rest and
personal time are 10 percent.
a. What is the normal time for the task?
b. What is the standard time for the task?
Define:
1.Severity Rate (SR)
2.Average Workdays Lost

For a time study of a health insurance claims-adjusting process, the analyst recorded the times. The job is divided
into four work elements, as shown in table. What is the appropriate sample size for estimating the time for element 2
within 7 percent of the true mean with 95 percent confidence?
