24 employees were randomly divided into two groups of 12. Both groups participated in a 2-week training period, but the first group also spent one extra day working on motivational material. At the end of the training period, the employees completed a series of tests and their performance was evaluated. If the sum of the ranks (rank) of the group that spent time with the motivational material was 136, what is the corresponding p-value for the hypothesis that the motivational material has no effect? What conclusion can you draw based on the p-value?
