Question

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

Answer 1

Answer: p-value ≈ 0.01

Step-by-step explanation: 1 of the 100 simulated result was at or below 60%.

Answer 2
