Glucose Tolerance

Glucose Tolerance Physicians depend on laboratory test results when managing medical problems such as diabetes or epilepsy. In a uniformity test for glucose tolerance, three different laboratories were each sent n_t = 5 identical blood samples from a person who had drunk 50 milligrams (mg) of glucose dissolved in water. The laboratory results (in mg/dl) are listed here:

a. Do the data indicate a difference in the average readings for the three laboratories?

b. Use Tukey’s method for paired comparisons to rank the three treatment means. Use a = .05.
