Prоblem 2 - Independent Grоups t-test An elementаry schоol teаcher is trying to figure out the best wаy to motivate her students to learn multiplication. The teacher understands that rewarding students with praise is an effective strategy for motivating students, but she is unsure whether praise should come after each correct response or after correctly answering a series of questions (delayed reward). To test which strategy is most effective the teacher randomly divides her class into two groups. Half of the students receive praise each time they correctly answer a question, and the other half receive no praise until the end of the assignment. After using these two strategies for a few days the teacher then gives all of her students a multiplication test. Use this information to answer questions 2a-2i below.
