The following times in seconds were observed for a particular one-element job using the continuous method: 12, 22, 35, and 50. The worker's rating factor is 1.1. What is the standard time for the job if an allowance of 20 percent is provided?
A) fewer than or equal to 14 seconds
B) greater than 14 but fewer than or equal to 15 seconds
C) greater than 15 but fewer than or equal to 16 seconds
D) greater than 16

The average time is calculated first: (12 + 22 + 35 + 50) / 4 = 119 / 4 = 29.75 seconds. The normal time is then found by multiplying the average time by the worker's rating factor: 29.75 * 1.1 = 32.725 seconds. The standard time includes an allowance, calculated as: Standard Time = Normal Time * (1 + Allowance Percentage) = 32.725 * (1 + 0.20) = 32.725 * 1.20 = 39.27 seconds. Therefore, the standard time is greater than 16 seconds.
