Key Observations
Not all values of p_samp_yes are the same.
This variability is less for when the sample size is large and more when the sample size is small.
When p_pop_yes = .80, nearly all the values for p_samp_yes are within about .09 of .80. [This last sentence is a HINT of where the +/- .09 came from in that “red” statement.]
