Research Question: Do crows remember the faces of people who bother them?

A volunteer wearing a caveman mask was scolded by 158 out of 444 crows he encountered, and the crows scolded a person in the neutral mask in 109 out of 922 encounters.In order to use the percentile method, you needed to generate a dot plot in StatKey. Which of the following best describes what's going on in this dot plot?

Choice 1: StatKey randomly generated many more samples crows, and each dot represents the average number of caveman masks each sample scolded.

Choice 2:StatKey randomly generated many more crows, and each dot represented the difference in the number of caveman and neutral masks that each crow scolded.

Choice 3:StatKey randomly generated many more crows, and each dot represented the difference in the proportion of caveman and neutral masks that each crow scolded.

Choice 4:StatKey randomly generated many more samples of crows, and for each sample, calculated the difference in the proportions of crows who scolded the caveman and neutral masks.

Can you explain which choice is correct and why?
