Perform hypothesis tests of means and proportions for large samples, using simulations to determine whether a sample mean (proportion) has a low likelihood of occurring.
Remarks
Example: A student wants to determine whether a certain coin is fair. She flips it 20 times, and notes that it came up heads 65% of the time (13 times out of 20). A computer simulation of the same experiment with a fair coin, repeated 100 times, yielded varying results, shown in the histogram below. How many of the 100 experiments done by the computer resulted in 65% or more heads?
