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 al. (2013). A magnetic pulse does not affect homing pigeon navigation: a GPS tracking experiment. The Journal of Experimental Biology, 216: 2192-2200.
See the article for further details on the experiment.
If you want more information about these procedures, I have a video introduction to inference procedures to two proportions available at: • An Introduction to Inference for Two ... .
