Final answer:
Current period productivity is calculated as 4.30 units/hour, while Previous period productivity is calculated as 4.00 units/hour. Productivity in both cases is determined by dividing the number of units produced by the total hours worked.
Step-by-step explanation:
To compute Current period productivity, divide the number of units produced by the total hours worked in the current period. So, for the current period the worker produced 215 units over 50 hours, which calculates to 4.30 units/hour (215 units ÷ 50 hours).
Similarly, for the Previous period productivity, divide the number of units produced by the total hours worked in the previous period. In this case, 160 units produced over 40 hours equals to 4.00 units/hour (160 units ÷ 40 hours).
These calculations are examples of measuring productivity, which is often expressed in terms of the output per hour worked as a common measure of U.S. productivity per worker. This is used to assess how much a worker contributes to the employer's output, and significant growth in this measure has been observed over time as depicted in various statistical figures.
