Consider the following analyses of cocaine by two different GC$-$MSprotocols. Is the new protocol providing values that are different than the old protocol $($p $<0\mathrm{.}05)?$ Assume that the analyst is the same in each case and that $"$s$"$ approaches"sigma" $($use population statistics rather than sample statistics$).$ All measures are in units of $\%$ w$/$w$.$Old $=6\mathrm{.}32,6\mathrm{.}21,6\mathrm{.}25,6\mathrm{.}38$New $=6\mathrm{.}30,6\mathrm{.}44,6\mathrm{.}45,6\mathrm{.}38$
