As the sample size increases, the value of the test statistic increases because the standard error decreases, making any observed effect more statistically significant. The power to detect an effect also increases because larger samples provide a more precise estimate of the population effect, reducing the likelihood of Type II errors. The estimate for the standard error decreases because standard error is inversely related to the square root of the sample size; as sample size increases, the standard error decreases.
