• Example 6.9.1– In a study of the effectiveness of a gluten-free diet in firstdegree relatives of patients with type I diabetics, Hummel etal. (A-22) placed seven subjects on a gluten-free diet for 12months. Prior to the diet, they took baseline measurements ofseveral antibodies and autoantibodies, one of which was thediabetes related insulin autoantibody (IAA). The IAA levelswere measured by radiobinding assay. The seven subjectshad IAA units of9.7, 12.3, 11.2, 5.1, 24.8, 14.8, 17.7– We wish to estimate from the data in this sample thevariance of the IAA units in the population from which thesample was drawn and construct a 95% confidence intervalfor this estimate.
