Question
All tests for statistical significance result in a test statistic.
a. What happens to the p-value (increases/decreases/stays the same) as the test statistic increases?
b. The p-value is a percentage (presented in decimal form). What does it tell us? (Refer to the end of module 9b slides for an explanation).
Expert Solution
Step 1
a)
The larger the absolute value of the t-value, the smaller the p-value, and the greater the evidence against the null hypothesis
Hence, the p-value decreases as the test statistic increases
