| 0% | I. For standardized test scores that are normally distributed with a mean of 500 and a standard deviation of 100, the z-score for a score of 650 is computed as $$\frac{650-500}{100} = 1.5$$.
II. The probability of scoring above 650 is then $$1 - \text{normalcdf}(-\infty,650,500,100) \approx 0.0668$$.
III. Similarly, the probability of scoring below 350 is $$\text{normalcdf}(-\infty,350,500,100) \approx 0.0668$$.
