Question: z-scores : White Blood Cells Count . Let X be the white blood cell count (WBC) per cubic millimeter of whole blood. Then X has a distribution that is approximately normal with mean \(\mu =7500\) and standard deviation \(\sigma =1750\). Convert the following x intervals into z intervals.

1. \(9000
2. \(X<6000\)
3. \[3500
4. \(z<1.44\,\,\,\Rightarrow \,\,\,X<7500+1750\times 1.44\,\,\,\Leftrightarrow \,\,\,X<10,020\)
5. \(2.19
6. \(0.25 \(\Leftrightarrow \,\,7937.5
7. If someone had a WBC count of 2500 would that be considered unusually or low?
