Unformatted text preview: adding chemical solutions to the brine. In one experiment, each of five antiscalants was added to an aliquot of brine and the solutions were filtered. A silica determination (ppm SiO2) was made on each filtered sample after a holding time of 24 hours. The results for the five samples were 1. 229ppm 2. 255ppm 3. 280ppm 4. 203ppm 5. 229ppm Estimate the mean amount of silicon dioxide present in the five antiscalant solutions. Give a 99% confidence interval for your estimate....
