The manager of a crew that installs carpeting has tracked the crew's output over the past several weeks, obtaining these figures:

Answer and Explanation:

a. The computation of labor productivity for each of the weeks is shown below:-

Week         Crew size      Yards installed      labor productivity

1                         4                    97                        24.25

2                         3                   71                          23.67

3                         4                   98                         24.5

4                          2                  54                         27

5                         3                   63                         21

6                         2                    52                         26

Therefore for computing the labor productivity for each week we simply divide the yards installed by crew size.

b. Perhaps even-sized crews are better than uncommon sizes and a crew of 2 seems to be performing best among the others
