Introductory Statistics: Inferences for Population Proportions (12.1-12.3) | Math with Professor V
Показать описание
Confidence intervals for one population proportion. Using notation to differentiate between sample and population proportions. The sampling distribution of the sample proportion, and the formula for confidence intervals of a proportion given alpha. Formula for the maximum error of the estimate. Examples finding confidence intervals by hand and using Statcrunch.
Hypothesis tests for one population proportion using a z-test. The procedure and assumptions necessary to perform a one-proportion z-test. Examples performing hypothesis tests by hand using the traditional method and using Statcrunch.
Inferences for two population proportions. Assumptions for the z test for two proportions. Example performing a z-test by hand and then additional examples using Statcrunch.
