It assesses whether the means of these groups are statistically different from each other or if any observed difference is due to random variation. The test compares the means of two groups while considering the variability within each group. We know that the population mean is actually 5 (because we set it that way), so we expect to reject the null hypothesis assuming our sample size is sufficiently large.
