Why do we not use a pooled proportion for the standard error here but we use. You can put this solution on YOUR website! the standard error is sd/sqrt (n) so here, the sd of the sample mean is 8/sqrt (4)=4, 95% of the measurements will be +/- 2 sd or 8 mg/dl away from the mean, so the interval is (119, 135) mg/dl,. Data may be loaded for a symbol that has options, or data may be entered manually. Any other bounds assigned based on distributions, will depend on assumptions on their parameters, which is not better than taking a guess. This is the sample standard deviation.
