    This z-score is Z = 0.44.

    Step-by-step explanation:

    The z-score measures how many standard deviations above or below the mean a measue of a normally distributed population or sample is.

    Each z-score has a pvalue, that is, the area to the left. We find these scores at the z table.

    Find the z-score that has area 0.67 to its left.

    This is the value of Z which has a pvalue of 0.67. So it is Z = 0.44.
