A manufacturing engineer studies the tensile strength of steel cables by testing 120 samples. The data reveals a mean strength of 2,450 pounds with a standard deviation of 180 pounds. However, the manufacturing process occasionally produces cables with internal flaws that reduce strength by 400-600 pounds, occurring in about 8% of production. These flawed cables are identifiable in the dataset. How should this bimodal tendency affect normal modeling decisions?
