Let x = red blood cell (RBC) count in millions per cubic millimeter of whole blood. For healthy females, x has an approximately normal distribution with mean u = 4.3 and standard deviation a = 0.5. The Standard Normal Distribution (-0, 0-1) -3 -2 -1 0 68% of area 95% of area 99.7% of area 2 3 Z (a) Convert the x interval, 4.5 < x, to a z interval. (Round your answer to two decimal places.) (b) Convert the x interval, x < 4.2, to a z interval. (Round your answer to two decimal places.) 2< (c) Convert the x interval, 4.0 < x < 5.5, to a z interval.

(Round your answer to one decimal place.) <X (f) Convert the z interval, -2.25 <z<-1.00, to an x interval. (Round your answers to one decimal place.) <X 4 (g) If a female had an RBC count of 5.9 or higher, would that be considered unusually high? Explain using z values. O Yes. A z score of 3.20 implies that this RBC is unusually high. O No. A z score of -3.20 implies that this RBC is unusually low. O No. A z score of 3.20 implies that this RBC is normal..
