occurrence sampling can be used to: determine machine utilizations determine allowances for time standards establish time standards all 3 answers are correct none of the 3 answers is correct question 32 2 pts occurrence sampling is often referred to as work sampling. true false question 33 2 pts for a relative accuracy of 10 % you need fewer observations to study an activity that occurs 10% of the time than one that occurs 90% of the time. true false
Answer
Brief Explanations:
- Question 31: Occurrence sampling, also known as work - sampling, can be used to determine machine utilizations, determine allowances for time standards, and establish time standards. It randomly observes a process at various times to estimate the proportion of time a machine or worker is busy or idle.
- Question 32: Occurrence sampling is indeed often referred to as work sampling. It is a technique for estimating the proportion of time spent on different activities.
- Question 33: The formula for the number of observations (n) in work - sampling is (n=\frac{z^{2}(1 - p)}{E^{2}p}), where (z) is the standard normal deviate related to the confidence level, (p) is the proportion of time the activity occurs, and (E) is the relative accuracy. For a fixed relative accuracy (E), when (p = 0.1) (activity occurs 10% of the time) compared to (p=0.9) (activity occurs 90% of the time), the number of observations (n) is smaller for (p = 0.1).
