My questions: is it correct?

(b). Use this information to calculate a production overhead absorption rate for Machining
department and for Assembly department based on machine hours and labor hours
respectively. Round off to nearest dollars for the above table.

My questions:

Does the Allocated costs in the question means the fixed overhead? In the textbook, there are material cost, labour cost etc but there is none here, how could I calculate (b)?

Thanks a lot for your help.
