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 are the two populations of interest in this study?
Population I: Students with poor reading skills who undergo the new reading program
Population II: The general population of readers
Population III: The students with poor reading skills who undergo regular reading classes.
Both A and C are correct
