A work sampling study was conducted to determine the proportion of the time a worker is idle. The following information was gathered on a random basis:

a. Based on these preliminary results, what percent of the time is the worker working?
b. If idle time is judged to be excessive, what additional categories might you add to a follow up work sampling study to identify the rootcauses?
