    Answer: C - 12

    Step-by-step explanation:

    Given : A researcher wishes to examine the influence of employment status (no job, part time, and full time) and academic class (Freshman, Sophomore, Junior, and Senior) on GPA.

    Factor 1 = employment status

    Factor 2 = academic class

    Choices for Factor 1 = 3

    Choices for Factor 2 = 4

    i. e. Number of treatments are possible in this experiment = (Choices for Factor 1) x (Choices for Factor 2) = 3 x 4 = 12 (Multiplication rule)

    Hence, there are 12 treatments are possible in this experiment.

    Thus, the correct answer is C - 12.
