A researcher has conducted a study that examines the relationship between exam score and IQ level of high school students in Wonderland. The relationship between IQ level and exam score of high school students in Wonderland was estimated as below in a linear format. (IQ level and exam scores are both measured in points) Exam score = 1.23 * IQ level - 60.72 (The p-value for the coefficient of IQ level is 0.01.) Base on the above equation, which of the following statements are true? (Select all that apply. There can be more than one answer.) Group of answer choices As a student's IQ level increases by one point, his or her exam score is expected to increase by 1.23 points. The expected exam score of a student with an IQ level of 0 points is 60.72 points. As a student's IQ level increases by one point, his or her exam score is expected to increase by 60.72 points. The expected exam score of a student with an IQ level of 100 points is 62.28 points
