Letx= red blood cell (RBC) count in millions per cubic millimeter of whole blood. For healthy females,xhas an approximately normal distribution with mean=3.8and standard deviation=0.4.(a) Convert thexinterval, 4.5<x, to azinterval. (Round your answer to two decimal places.) <z (b) Convert thexinterval,x<4.2, to azinterval. (Round your answer to two decimal places.) z< (c) Convert thexinterval, 4.0<x<5.5, to azinterval. (Round your answers to two decimal places.) <z< (d) Convert thezinterval,z<1.44, to anxinterval. (Round your answer to one decimal place.) x< (e) Convert thezinterval, 1.28<z, to anxinterval. (Round your answer to one decimal place.) <x (f) Convert thezinterval,2.25<z<1.00, to anxinterval. (Round your answers to one decimal place.) <x< (g) If a female had an RBC count of 5.9 or higher, would that be considered unusually high? Explain usingzvalues.Yes. Azscore of 5.25 implies that this RBC is unusually high.No. Azscore of5.25 implies that this RBC is unusually low. No. Azscore of 5.25 implies that this RBC is normal.
