Using a chemical procedure called differential pulse
Chapter 11, Problem 31E(choose chapter or problem)
Using a chemical procedure called differential pulse polarography, a chemist measured the peak current generated (in microamperes, \(\mu A\)) when solutions containing different amounts of nickel (measured in parts per billion, ppb) are added to different portions of the same buffer.8 Is there sufficient evidence to indicate that peak current increases as nickel concentrations increase? Use \(\alpha=.05\).
