    Answer:

    The solution is 1,300-1,900

    Step-by-step explanation:

    Simply put:

    The standard deviation is 100. Because the range is 3 standard deviations, you add and subtract 300 from 1,600 instead of the normal 100.

    So,

    1,600 – 300 = 1,300

    1,600 + 300 = 1,900

    So, your answer is the third option: Between 1,300 and 1,900
