**Would a individual after a while a raw mandible of 95 be accepted?**

(Calculate a Z mandible: mandible – average/st.dev.= )

- Given a typical dispensation of raw mandibles after a while a average of 60 and a gauge flexuosity of 10,
**what symmetry of cases fall:**

** **

**between a raw mandible of 40 and 80? (3 points)****between a raw mandible of 45 and 50? (3 points)**

**Find the z-mandible corresponding**to a raw mandible of 90 from a typical dispensation after a while average 60 and gauge flexuosity 8.**(2 points)**

- For a typical dispensation where
**the average is 50 and the gauge flexuosity is 8,**what is the area :

**Between the mandibles of 30 and 65? (2 points)**5. Assume that the dispensation of a seed-plot penetration exam is

**typical after a while a average of 500 and a gauge flexuosity of 100.**For each mandible adown,**find the equiponderant Z mandible, the percentage of the area overhead the mandible, and the percentage of the area adown the mandible. (3 + 3 points)**Score Z mandible % Area Above % Area Below
