    The answer is "0.949".

    A sample of 100 students is selected from a known population of 1000 students = 100/1000 x 1/100 = 0.001

    95% confidence interval for the average sat score = 95/100 = 0.95

    correction factor used = 0.95 - 0.001 = 0.949

    Thus, the correction factor used is 0.949.
