For a lower tail test, the p-value is the probability of obtaining a value for the test statistic at least as
A) small as that provided by the sample.
B) large as that provided by the sample.
C) small as that provided by the population.
D) large as that provided by the population.
P-value
A statistical measure that indicates the probability of obtaining the observed results of a test, assuming that the null hypothesis is true.
Test Statistic
A statistic (a quantity derived from the sample) used in statistical testing to decide whether to reject the null hypothesis.
- Acquire knowledge on the probability of test statistic values and examine p-values in different scenarios of hypothesis testing.

Final Answer :
A
Explanation :
In a lower tail test, we are interested in whether the sample provides evidence that the true population parameter is smaller than some hypothesized value. Therefore, the p-value is the probability of obtaining a value for the test statistic at least as small as that provided by the sample.
Learning Objectives
- Acquire knowledge on the probability of test statistic values and examine p-values in different scenarios of hypothesis testing.
