# Approximate Confidence Intervals for Large Samples

Approximate Confidence Intervals for Large Samples is a part of the VCE Maths Methods topic Probability and Statistics. In this post, we use the approximate confidence interval as an interval estimate for p , where z is the appropriate quantile for the standard normal distribution. We will also look at understanding how to find the Z-Score from the confidence interval.

### Confidence Intervals and Sample Proportions

Watch this video to understand how to calculate confidence intervals for sample populations.

The following video explains how to find the confidence intervals using the mean and proportions. This will allow us to calculate an interval that estimates a population parameter.

### Confidence Intervals and the Mean

This next video looks at how to calculate the confidence interval for a mean.

### What is a Z-Score?

This next video helps us to understand what a Z-Score is, and how to find it given the confidence intervals.
