    Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion of 5% in the smaller area. (90% leaves 5% in each direction.)

    90% confidence interval = mean ± 1.645(SEm)

    SEm = SD/√(n-1)

    This gives confidence interval for means rather than individual scores.
