An experiment was carried out to compare the abilities of two different solvents to extract creosote impregnated in test logs. Each of eight logs was divided into two segments, and then one segment was randomly selected for application of the first solvent, with the other segment receiving the second solvent.

Calculate a CI using a confidence level of roughly 95% for the difference between the true average amount extracted using the first solvent and the true average amount extracted using the second solvent.

Log Solvent 1 3.92 3.79 3.70 4.08 3.87 3.95 3.55 3.76 Solvent 2 4.25 4.20 4.41 3.89 4.39 3.75 4.20 3.90
