    Question

    A researcher expects male students to perform better on a given test than female students. To investigate this, he invites 13 males and 17 females to do a mathematical test. All participants make exactly the same test and are given all the time they need to complete it. The researcher then scores the correct answers and executes a t-test in SPSS. The output of the SPSS analysis of this test is below.


    1. TRUE: Cutoff = 1.701 with 28 degrees of freedom
    2. FALSE: Cutoff = 1.699 with 29 degrees of freedom
    3. FALSE: Cutoff = 2.049 with 28 degrees of freedom
    4. FALSE: Cutoff = 2.045 with 29 degrees of freedom
