◦ the level of confidence, the z-value, and normal time.
◦ actual time, normal time, and standard time.
◦ the level of confidence, the z-value, and the work sampling idle percent.
◦ needed accuracy, desired confidence, and standard deviation of the initial sample.

Question 2

A manager who is conducting a time study now needs an accuracy of ±0.1 minutes, rather than ±0.2 minutes as in the past. Because of this change in accuracy, the adequate sample size becomes
◦ one-fourth as large.
◦ four times as large.
◦ eight times as large.
◦ twice as large.
