Question

Let x = red blood cell (RBC) count in millions per cubic millimeter of whole blood. Suppose for healthy females, x has an approximately normal distribution with mean $\mu$ = 4.3 and standard deviation $\sigma$= 0.8 Convert the following x interval from a laboratory test to a z interval. 1.1 > x A)-4 > z B)1 < z C)-4 < z D)2 < z E)4 < z

Quizplus · Accepted Answer

To convert x to z, we use the formula:
z = (x - μ) / σ
Plugging in the values given in the problem, we get:
z = (1.1 - 4.3) / 0.8
z = -4
Therefore, the answer is A, -4 > z.
