What do you understand by "Design of an Experiment"? Physicians depend the laboratory test results when managing the medical problems such as diabetes or epilepsy. In an uniformity test glucose tolerance, three different laboratories were sent n_t=5 identical blood samples from a person who had drunk 50 mg. of glucose dissolved in water. The laboratory results are listed below:

Lab 1
Lab 2
Lab 3
12.1
9.3
10.0
11.7
11.1
10.5
10.9
10.7
10.1
10.2
10.9
11.0
10.6
9.0
10.4
