    Answer:

    68% of the area

    Step-by-step explanation:

    The Empirical Rule states that, for a normally distributed random variable:

    Approximately 68% of the measures are within 1 standard deviation of the mean.

    Approximately 95% of the measures are within 2 standard deviations of the mean.

    Approximately 99.7% of the measures are within 3 standard deviations of the mean.

    In this question:

    By the Empirical Rule, 68% of the area is within 1 standard deviation of the mean.
