The average lethal blood concentration of morphine is estimated to be 2.5 µg/mL with a standard deviation of 0.95 µg/mL. The data is normally distributed. Examine the range of values 0.05 to 4.95 µg/mL. Answer the following questions and provide the appropriate calculations (13 points):

a. What is the probability associated with the range lethal morphine blood levels?

The probability associated with the range lethal morphine blood levels is 0.9902.

Step-by-step explanation:

Let X = lethal blood concentration of morphine.

The random variable X is normally distributed with parameter μ = 2.5 μg/ mL and σ = 0.95 μg/ mL.

Compute the probability of X within the range 0.05 to 4.95 μg/ mL as follows:

*Use a z-table for the probability.

Thus, the probability associated with the range lethal morphine blood levels is 0.9902.
