A manufacturing company is making smoke detectors. They want to conduct a study to determine how well the smoke detectors work. The null hypothesis in this study is that the smoke detectors will not work. In this case, what would be the Type I error? In this case, what would be the Type II error? Which do you think is the more costly error? Why?
