    Question

    A psychologist attached to a prison is interested in the relationship between crime and intelligence. A crime index (between 0 and 50) is formulated that takes into account the severity and frequency of crimes committed. Intelligence is measured with a standardized IQ test. Eighteen convicted juveniles participate in this study. SPSS was used to describe the relationship between the two variables. Part of the SPSS output is shown below.


    1. FALSE: Ŷ (intelligence) = 73.546 - 0.465 x Crime
    2. TRUE: Ŷ (crime) = 73.546 - 0.465 x Intelligence
    3. FALSE: Ŷ (crime) = 73.546 + 9.308 x Intelligence
    4. FALSE: Ŷ (intelligence) = -0.786 x Crime
