    Step-by-step explanation:

    Given that Majesty Video Production Inc. wants the mean length of its advertisements to be 30 seconds

    Let X be the mean length of advts.

    X is N (30, 2)

    n = 16

    Std error of sample = 2/sqrt 16 = 0.5

    The sample mean also will be normal with mean - 30 and std dev = 0.5

    So bell shaped symmetrical and uni modal
