A study was done by Sananman and Lear in the 1960s to monitor the amount of iron (mg/L) in the water in the Chesapeake Bay. They compared the amount of iron from a depth of 10 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 (-0.20, -0.13). Interpret the confidence interval. We are 95% confident that . . .
