Mr. Jensen told his class that he plays basketball frequently, and he claimed that he could make 80% of his free- throw attempts. The class suspected that Mr. Jensen was actually less than an 80% free-throw shooter. To test
their theory, they had Mr. Jensen shoot a series of 40 free-throws. He made p= 60% of them.
To see how likely a sample like this was to happen by random chance alone, the class performed a simulation.
They simulated 100 samples of n = 40 free-throws, where each free-throw had an 80% chance of being made.
They recorded the proportion of free-throws made in each sample. Here are the sample proportions from their
100 samples:
