Confidence Intervals - homepages.math.uic.edu

Confidence Interval for Proportion p is the population proportion (of a certain characteristic) To find a C% confidence interval, we need to know the z-score of the central C% in a standard-normal distribution. Call this 'z' Our confidence interval is p±z*SE(p) p is the sample proportion SE(p)=√(p(1-p)/n

On the other hand, 2.5% of the time the highest value in the confidence interval will

The 95% confidence interval for this example is between 76 and 84. The 99.7% confidence interval for this example is between 74 and 86. Therefore, the larger the confidence level, the larger the interval. There is a trade-off between the two. If researchers want to be very certain that their interval includes the
