Show answer & explanation
Correct answer: D
The p-value is defined as the probability of observing results as extreme or more extreme than currently observed, assuming that the null hypothesis is true. It measures the strength of evidence against the null hypothesis based on sample data, rather than the probability that the null hypothesis itself is true.
