A study examined the effects of fatigue on driving performance. Based on the results, the researchers rejected the null hypothesis and concluded that the group who were fatigued had worse driving performance than those in the non-fatigued group. In reality, the majority of fatigued drivers produce significantly slower reaction times and worse decisions while driving than the non-fatigued driver population. What has occurred? The researchers made a correct decision The researchers made a Type II error The researchers failed to identify a confounding variable The researchers made a Type I error
