Suppose a researcher wants to study the effectiveness of a new reading program for students who have not acquired the necessary reading skills by the time they reach the 8th grade. A randomly selected group of 50 students from a local junior high with poor reading skills will undergo a special reading program. Another group of 50 randomly selected students with poor reading skills will undergo regular reading classes. A month later, the reading skills of all 100 students are assessed to determine whether the program was successful.

What is the research hypothesis in this example?

- The means of Population 1 and Population 2 are the same

- The mean of Population 2 is greater than Population1

- The means of Population 1 and Population 2 are different

- The mean of Population 1 is greater than the mean of Population 2
