A company produces precision 1-meter (1000 mm) rulers. The actual distribution of lengths of the rulers produced by this company is normal with mean m and standard deviation 0.02 mm.
Suppose I select a simple random sample of four of the rulers produced by the company and I measure their lengths in millimeters. The results of these four measurements are as follows.
1,000.01 999.98 1,000.00 1,000.01
