Type I error: Washers used in a certain application are supposed to have a thickness of 2 millimeters. A quality control engineer measures the thicknesses for a sample of washers and tests Ho: μ = 2 versus H₁: μ # 2. a. If a Type I error is made, what conclusion will be drawn regarding the mean washer thickness?
