Final answer:
The service provider has made several errors in this scenario that can affect Mike's progress and hinder the effectiveness of therapy.
Step-by-step explanation:
The service provider has erred by not providing clear instructions on all the exercises in the booklet, not giving Mike the booklet with all the exercises, not checking if Mike was performing all the exercises, and not scheduling enough therapy sessions for Mike.
These errors can negatively impact Mike's progress and hinder his ability to fully benefit from the therapy. It is important for service providers to ensure clear communication, provide all necessary materials, monitor performance, and schedule enough sessions for effective therapy.
