Question

What is the z-score for a patient who takes 7 days to recover? (choose the closest possibility.)

Answer 1

Based on the time it took the patient to recover and the mean and standard deviation, the z-score is 1.5.

What is the z-score?

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.
