Question Answer
Statistical Inference using statistics computed from a sample to make statements about unknown population parameters Sample Mean --> used to make inferences about population mean Sample proportion --> used to make inference about the population proportion
Sampling Distribution the distribution of values taken by the statistic in a large number of simple random samples of the same size 'n' from the same population
