They compared the amount of iron from a depth of 0 feet (group 1) to a depth of 100 feet (group 2). The researchers were interested in determining if the amount of iron was different at the two depths. The 95% confidence interval to compare the two depths is (-0.196, -0.129). Interpret the confidence interval. We are 95% confident that . . .
