Question
In work sampling to measure idling activity, what is the number of samples
required? In this problem, desired accuracy (or error limit) is 10%, confidence interval/level
is 92%. The standard normal curve table is at the last page. To help you recall the equation,
the one in our lecture note is:
N= Z^2 x (p(1-p)/S^2)
The table of observations is
State Total Observations
Working 60
