A software development team is preparing for User Acceptance Testing (UAT) for a new e-commerce platform. The team has identified three key user groups: customers, administrators, and support staff. Each group has distinct requirements and expectations from the system. During UAT, the team decides to prioritize testing scenarios based on the frequency of use and the criticality of tasks performed by each user group. If the customers perform 60% of the tasks, administrators perform 30%, and support staff perform 10%, how should the team allocate their testing resources to ensure comprehensive coverage? Specifically, if they have 100 testing hours available, how many hours should they ideally allocate to each user group based on their usage percentages?
