Based on the time it took the patient to recover and the mean and standard deviation, the z-score is 1.5.
<h3>What is the z-score?</h3>
The z-score for this patient who takes 7 days to recover can be found as:
= (Time taken to recover - Mean) / Standard deviation
Solving for the z-score gives:
= (7 - 5.2) / 1.2
= 1.8 / 1.2
= 1.5
The first part of the question is:
The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.2 days and a standard deviation of 1.2 days.
