A theory suggests that 45 out of 50 samples would contain the population mean. When running the lab/samples I found 96%. 2 of the confidence intervals did not contain the population mean. Why? Is this because the population parameter is an unknown constant and the invert constructed from a sample is random.

Consider random samples of size 86 drawn from population A with proportion 0.47 and random samples of size 64 drawn from population B with proportion 0.19 . Find the standard error of the distribution of differences in sample proportions, p^A-p^B. Round your answer for the standard error to three decimal places.
