Transcribed Image Text:### Lower Limb Surgery
The study "Intrathecal Sufentanil versus Fentanyl for Lower Limb Surgeries – A Randomized Controlled Trial" (Journal of Anaesthesiology Clinical Pharmacology, Vol. 27, Issue 1, pp. 67–73) by P. Motiani et al. compares two different agents, intrathecal sufentanil and fentanyl, used in enhancing the anesthesiology of patients receiving major lower limb surgery. One variable compared between the two agents was the amount of blood loss during the surgery.
Based on the study, we will assume that, using fentanyl, the amount of blood loss during major lower limb surgery is normally distributed with a mean of 283.3 ml and a standard deviation of 83.3 ml. Find the percentage of patients whose amount of blood loss during major lower limb surgery using fentanyl is:
a. less than 304 ml.
b. between 221 and 429 ml.
c. more than 450 ml.
Expert Solution
Step 1
Consider that the mean and standard deviation of a random variable X are µ and σ, respectively.
Thus, the z-score of that random variable X is z = (X – µ)/σ.
