8.3 Inference for a Proportion: An Example of a Confidence Interval and a Hypothesis Test

I work through an example of a confidence interval and a hypothesis test for a single proportion, using normal approximation methods (Z test and confidence interval). The male birth rate data is from: Koshy et al. (2010). Parental smoking and increased likelihood of female births. Annals of Human Biology, 37(6): 789–800.

8.5 An Introduction to Inference for Two Proportions

I discuss the sampling distribution of the difference in sample proportions, and confidence intervals and hypothesis tests for the difference in population proportions (using large sample Z procedures based on the normal approximation). The male birth rate data is from: Koshy et al. (2010). Parental smoking and increased likelihood of female births. Annals of Human … Read more

8.6 Inference for Two Proportions: An Example of a Confidence Interval and a Hypothesis Test

I work through an example of a confidence interval and a hypothesis test for the difference in population proportions (based on the normal approximation). The example involves an experiment investigating a possible effect of magnetic pulse on the ability of homing pigeons to navigate. The data used in this video is taken from: Holland et … Read more
