Answer:
The probability associated with the range lethal morphine blood levels is 0.9902.
Step-by-step explanation:
Let <em>X</em> = lethal blood concentration of morphine.
The random variable <em>X</em> is normally distributed with parameter <em>μ</em> = 2.5 μg/ mL and <em>σ</em> = 0.95 μg/ mL.
Compute the probability of <em>X</em> within the range 0.05 to 4.95 μg/ mL as follows:
*Use a <em>z</em>-table for the probability.
Thus, the probability associated with the range lethal morphine blood levels is 0.9902.
