Overview

Sampling and Estimation is the culmination of earlier work on probability and random variables. Statistical inference is one of the most imporant parts of statistics, in which the goal is to estimate an unknown parameter associated with a population using a sample of data drawn from that population. We will explore estimating proportions in two-outcome populations.

Topics & Concepts We Cover

This learning program is made up of the following 2 topics, broken down into 14 concepts.

Random Sampling 9 concepts
1. Use the sampling distribution to calculate probabilities, including conditional probabilities
2. Construct a probability distribution table which summarises a sampling distribution using selections for small populations
3. For large samples, use the normal approximation to the binomial distribution to determine the mean and standard deviation
4. Determine the sample proportion
5. Determine the population proportion
6. Use the binomial random variable of a sample proportion to find the mean and standard deviation of a large population
7. Use the sampling distribution to find the mean and standard deviation of a small population
8. Construct a probability distribution table which summarises a sampling distribution using the binomial distribution for large populations
9. Discuss random sampling
Confidence Intervals 5 concepts
1. Find a point estimate for a population proportion
2. Compare confidence intervals
3. Find an approximate C% confidence interval for a population proportion
4. Find an approximate 95% confidence interval for a population proportion
5. Application of the rule for a margin of error with a 95% confidence interval
