In a test of hypothesis, a small P-value provides evidence

Select one:

a. against the null hypothesis in favor of the alternative hypothesis.

b. against the null hypothesis and the alternative hypothesis.

c. for the null and the alternative hypothesis.

d. against the alternative hypothesis in favor of the null hypothesis.

Solution

When P-value is less than level of significance, we reject the null hypothesis. For example: If P-value is 0.0002 and level of significance is 0.01, we will reject the null hypothesis.

That is small P-value is in favor of alternative hypothesis and against the null hypothesis.

hence, option (a) is correct.
