Question

Asked Apr 12, 2019

The following are the normalized levels of a critical protein in 12

samples of blood:

8*.*2 *, *4*.*7 *, *10*.*3 *, *11*.*7 *, *18*.*3 *, *5*.*9 *, *3*.*8 *, *18*.*9 *, *7*.*6 *, *14*.*2 *, *9*.*8 *, *16*.*4

Compute the sample mean, the sample median, and the sample

standard deviation.

Step 1

**Mean and standard deviation:**

Step 2

**Median:**

The median is the middle-most value in a data set. For even number of observations, the median is the mean of the two middle-mist values, when the data is arranged in an ascending or descending order.

The data in ascending order is:

3.8, 4.7, 5.9, 7.6, 8.2, 9.8, 10.3, 11.7, 14.2, 16.4, 1...
