Final answer:
To calculate equivalent units of production using the weighted average method, you need data on completed units, units in process, and their completion percentages. No actual calculation can be given without specific information. Unrelated content in the question was noted but not applied to the response.
Step-by-step explanation:
To calculate the assembly department's equivalent units of production for materials and for conversion using the weighted average method, you would need to have specific data about the number of units completed, the amount of materials, labor, and overhead applied to units in process at the beginning and end of the period, and the degree of completion for the units in process.
Typically, the calculation involves summing the number of completed units with the equivalent units in work-in-process (WIP), where equivalent units are the WIP units multiplied by their percentage of completion.
The materials and conversion costs (labor and overhead) may have different percentages of completion depending on the stage of the process. Unfortunately, without the actual figures, we cannot perform the specific calculation.
It appears there are typographical errors or unrelated content provided in the question that does not apply to the calculation of equivalent units of production, such as unit conversion factors and weight calculations.
