A student determined the concentration of a sodium hydroxide solution, and after four runs she reported a value of 0.1053 M with 98% confidence limits of ± 0.0014 M. Assuming that no systematic errors were involved, which statement is true? The true value (for the concentration of sodium hydroxide in the solution) must be between 0.1039 M and 0.1067 M. There is a 2% probability that the true value is greater than 0.1067 M. If the student repeats the analysis 100 more times, 98 of the values will be between 0.1039 and 0.1067 M. There is a 98% probability that the true value lies between 0.1039 M and 0.1067 M.
