    0.683

    Step-by-step explanation:

    We have to find P (-1
    For this purpose, we use normal distribution area table

    P (-1
    Using normal area table and looking the value corresponds to 1.0, we get

    P (-1
    P (-1
    Rounding the answer to three decimal places

    P (-1
    So, 68.3% of the z-scores will be between - 1 an 1.
