Question

Leaf surface area is an important variable in plant gas-exchange rates. An article included an analysis of dry matter per unit surface area (mg/cm3) for trees raised under three different growing conditions. Let u1, Au2, and Au3 represent the true mean dry matter per unit surface area for the growing conditions 1, 2, and 3, respectively. The given 95% simultaneous confidence intervals are based on summary quantities that appear in the article. H3 Difference H2 H3 Interval (-2.08, -0.08) (-1.92, 0.08) (-2.05, -0.05) Which of the following four statements do you think describes the relationship between Au1, Au2, and Au3? O Al1 A 2, and Au 3 differs from Au1 and u2. O H1 A13, and Au2 ers from 1 and Au3. O u2 3, and Ai differs from Au2 and A13. H1 H2 H3

Explanation / Answer

here from above confidence interval as mu2 has interval with both mu2 and mu3 at one side of 0;

hence option mu1=mu3; and mu2 differs from mu 1 and mu3
