To find the probability of a selected x-value being at most 35, you need to find the corresponding z-score and then use a z-score table. The area below the curve for the z-score is then the probability that the value will be at most 35.

To find the corresponding z-score, use the formula \(\displaystyle{z}=\frac{{{x}−μ}}{

To find the corresponding z-score, use the formula \(\displaystyle{z}=\frac{{{x}−μ}}{
