Answer:
Option a is right
the probability that we would see a test statistic this extreme or more if the null hypothesis were true.
Step-by-step explanation:
In hypothesis testing we fix null and alternate hypothesis. The conclusion of the test depends on the p value of the test.
The p value also known as probability value is the estimated probability of rejecting the null hypothesis when it is actually true.
It can be said the extreme value i.e. if p value is atleast this much we accept null hypothesis.
Hence out of the options given correct choice is
the probability that we would see a test statistic this extreme or more if the null hypothesis were true.
