You have carried out five separate titrations to determine the
concentration of a sodium hydroxide solution and obtained the
values: 0.0325 M0.0325 M , 0.0331 M0.0331 M , 0.0322 M0.0322 M , 0.0346 M0.0346 M ,
and 0.0328 M0.0328 M .
Calculate the š¯‘„Q value for the highest and lowest
values in this set of measurements.
š¯‘„high=Qhigh=
š¯‘„low=Qlow=
Comparing these š¯‘„Q values to the critical
value (š¯‘„c)(Qc) for the š¯‘„Qā€‘test, can either of these
values be rejected as an outlier at the 95%
confidence level?
Reject š¯‘„highQhigh as an outlier.
Reject š¯‘„lowQlow as an outlier.
Neither value can be rejected.
