Five samples of size three (3) were collected for a variable measurement. All sample data were greater than or equal to 4. The sample means and sample ranges are:

Sample number 1 2 3 4 5
Sample mean 5.0 4.9 5.0 5.2 6.0
Sample range 0.2 0.4 0.1 0.3 0.0

The sample data are identical in which sample?

How do I figure out which sample mean and range are identical?

Thanks!

The sample data are identical in sample number 5 since there is no range.
