    68.2% of the data falls within 1 standard deviation of the mean

    Step-by-step explanation:

    When we look at the curve for standard deviation, 34.1 % falls within 1 standard deviation below the mean and 34.1 % falls within 1 standard deviation above the mean.

    34.1 + 34.1 = 38.2 %

    68.2% of the data falls within 1 standard deviation of the mean
