Answer and Explanation:
The computation of the labor productivity per hour for each week is shown below:
As we know that
Labor productivity = Total shirts ÷ Total hours
For week 1
= 168 ÷ 24
= 7 shirts per hour
For Week 2
= 130 ÷ 46
= 2.83 shirts per hour
For Week 3
= 162 ÷ 62
= 2.61 shirts per hour
For Week 4
= 125 ÷ 51
= 2.45 shirts per hour
For Week 5
= 131 ÷ 45
= 2.91 shirts per hour
