    Use the formula:
    se = (s/√n) x √(N-n/N-1)

    se = 15/√59.5 x (√(140-56)/139)

    se = 1.512

    Hey Grant,

    I'm just the answer Nazi. You divided by the mean (59.5), not the sample population (56) to find the sample error, so your answer is slightly off. I think it should be

    se= 15/√56(√[(140-56)/139)

    = 1.558

    I think...correct me if I am wrong
