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

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: youtu.be/g0at6LpYvHc.
