Solution Volumes
An analytical chemist wanted to use electrolysis to determine the number of moles of cupric ions in a given volume of solution. The solution was partitioned into n = 30 portions of 0.2 mL each. Each of the n = 30 portions was tested. The average number of moles of cupric ions for the n = 30 portions was found to be 0.185 mole; the standard deviation was 0.015 mole.
-Refer to the Solution Volumes statement. Describe the distribution of the measurements for the n = 30 portions of the solution using Tchebysheff's Theorem.
