The alternative hypothesis posits that there is a significant effect or difference in a population parameter, contrary to the null hypothesis which suggests no effect or difference.
The 'null hypothesis' is a fundamental concept in statistics and scientific research. It posits that there is no effect or no difference between groups or variables being studied. This hypothesis serves as the default assumption that any observed effect is due to random variation or chance.
