_____ < x < ____
(g) If a female had an RBC count of 5.9 or higher, would that be considered unusually high? Explain using z values.
____< z
(b) Convert the x interval, x < 4.2, to a z interval. (Round your answer to two decimal places.)
z < ____
(c) Convert the x interval, 4.0 < x < 5.5, to a z interval. (Round your answers to two decimal places.)

(g) If a female had an RBC count of 5.9 or higher, would that be considered unusually high? Explain using z values.
A-Yes. A z score of 3.83 implies that this RBC is unusually high.
B-No. A z score of −3.83 implies that this RBC is unusually low. C-No. A z score of 3.83 implies that this RBC is normal.
