Problem 4: A study published in Chemosphere reported the levels of the dioxin TCDD of 20 Massachusetts Vietnam veterans who were possibly exposed to Agent Orange. The TCDD levels in plasma and in fat tissue are listed in Table 9.1 Find a 95% confidence interval for μι μ, where μί and μ2 represent the true mean TCDD levels in plasma and in fat tissue, respectively. Assume the distribution of normal the differences to be approximately Table 9.1: Data for Example 9.13 TCDD TCDD Levels in Levels in Veteran Plasma Fat Tissue dj Veteran Plasma Fat Tissue TCDD Levels in TCDD Levels in 1 2.5 4.9 3.1 2.1 3.5 3.1 1.8 6.0 3.0 36.0 4.7 5.9 4.4 6.9 7.0 4.2 10.0 5.5 41.0 4.4 12 13 14 15 16 17 18 19 20 6.9 3.3 4.6 1.6 7.2 1.8 20.0 2.0 2.5 4.1 7.0 2.9 4.6 1.4 7.7 1.1 11.0 2.5 2.3 2.5 3 7 10 Hint: sa- 2.9773
