Chapter 6: Q.6.60 (page 389)

The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.3days and a standard deviation of 2.1days.

What is the median recovery time?

a. 2.7

b. 5.3

c. 7.4

d. 2.1

Short Answer

Expert verified

The median recovery time is 5.3years and the correct answer is option (b)

Step by step solution

01

Given information

Given in the question that

Mean=5.3

Standard deviation=2.1

02

Solution

Here we know that in normal distribution the mean, median and mode have the same value.

So the median recovery time will be equal to the mean recovery time.

That is the value of median recovery time is 5.3years
