(f) Convert the z interval, -2.25 <z< -1.00, to an x interval. (Round your answers to one decimal place.)
(9) If a female had an RBC count of 5.9 or higher, would that be considered unusually high? Explain using z values.
O Yes. Az score of 7.00 implies that this RBC is unusually high.
O No. Az score of -7.00 implies that this RBC is unusually low.
O No. A z score of 7.00 implies that this RBC is normal.
