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

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
