For the last activity in this Table, and considering a crew size of $6$ rebar people working on the elevated slab, can we determine the overall crew productivity level taking into account this crew size? $($Provide the best answer$)$:

Yes, it is clearly determined on an individual basis

No$,$ crew productivity level cannot be determined based on the given data

Crew productivity level was determined as an average output$/$day$,$ so the assumption is that crew will produce same amount of work on a daily basis to achieve the plan quantities in $6$ days

Since the Superintendent$/$PM knows there are some rainy days coming, the assumptions are not realistic
