The empirical rule does not apply to all normally distributed variables.

A centro de los dos círculos. \( \frac{\mathrm{AB}}{\mathrm{AC}}=\frac{1}{3} \) Si el radio del circulo mayor es 12 cm , determine el area sombreada.

regards to this experiment: A. Sketch a sample standard curve (with 3 data points) that has a poor (low) \( R^{2} \) value, but still provides an accurate density determination. B. Should you be confident when using equations with low \( R^{2} \) values? How cou you improve the \( R^{2} \) value without redoing any previous data points. C. Will a high \( R^{2} \) value always provide an accurate answer? Explain with a plotted example.
