    If the mean = 54, 1 standard deviation (+1σ) above the mean = 54+6 = 60

    1 standard deviation (-1σ) below the mean = 54 - 6 = 48

    68% of the data of a normal distribution lies between - 1σ and + 1σ: between 48 - 60 requests

    between 54 - 60 requests (between the mean and + 1σ) is half of this percentage: 68/2 = 34%

    Answer: 34%
