    95% Confidence Interval

    Suppose you calculate a 95% confidence interval for the mean hemogloblin level of students based on a sample of 100 students. THe result is:
    10<<16 g/L.

    Is this correct?
    P(<10) and P(>16) = .05

    Thanks for your help.

    Usually it with a symetric interval it means:

    P(<10)=0.025, and P(>16)=0.025,

    That is the interval contains 95% of the distribution, so 2.5% lie outside
    above, and below the interval.
