    C.) 0.9656

    Step-by-step explanation:

    Using a z-table look for - 1.82 and we obtain : 0.0344. So what's the probability that z > - 1.82 is the same as saying when is z > 0.0344? Since we're talking about probabilities of an outcome from ranging from 0% to 100% meaning 0 through 1 in decimals then:

    1 - 0.0344 = 0.9656

    So the probability that z>-1.82 is C.) 0.9656
