Interpret the p-value

In the previous exercise, you conducted a hypothesis test to evaluate whether the median scores on math and science exams are different. The observed median difference and p-value that you calculated are in your workspace as scorediff_med_obs and scorediff_p_value.

Which of the following is the correct definition of the p-value of this hypothesis test?

Possible answers

The probability that there is no difference between the median math and science scores.

The probability that the median math score is higher than the median science score.

The probability of getting a random sample of 200 high school students where there is no difference between the median math and science scores, if in fact the median difference between their math and science test scores is at least 1.
