(Solution) - Let x red blood cell RBC count in millions -(2025 Original AI-Free Solution)
Paper Details
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 ? = 4.8 and standard deviation ? = 0.3 (based on information from Diagnostic Tests with Nursing Implications, edited by S. Loeb, Springhouse Press). Convert each of the following x intervals to z intervals:
(a) 4.5 < x
(b) x < 4.2
(c) 4.0 < x < 5.5
Convert each of the following z intervals to x intervals:
(d) z < ?1.44
(e) 1.28 < z
(f) ?2.25 < z < ?1.00
(g) If a female had an RBC count of 5.9 or higher, would that be considered unusually high? Explain using z values and Figure 7-12.
