In order to interpret the p-value associated with hypothesis testing about the population mean μ,it is necessary to know the value of the test statistic.

P-Value

The probability of observing results at least as extreme as those in a data set, given that the null hypothesis is true.

Hypothesis Testing

A statistical method used to decide whether a hypothesis about a parameter in a population is supported by the data gathered from a sample.

Test Statistic

A numerical value employed in statistical hypothesis testing for deciding if the null hypothesis should be discarded.
