Bobby Flay is responsible for assigning steel workers to a structural steel infrastructure construction task. Having taken Project Management at the University of Portland, he understands the importance of managing risk. To ensure that the task takes place as scheduled, Bobby must ensure that there are at least 8 steel workers available at the start of the task. Based on analysis of similar tasks, he estimates that steel workers will show up for the task with probability 0.9. If Bobby wants to be 97% sure that there are enough tasks to begin as scheduled, he should assign ______ steel workers to the task.
