While working in your lab, you come across four unlabeled boxes that each contain several salamander skulls. You notice that the skull samples differ in jaw size and decide to measure and plot the ranges and averages of jaw sizes in each of the samples (i.e. boxes) of skulls. The resulting data are shown below. min |max squamosal average dentary Sample 1 Sample 2 Sample 3 Sample 4 small Jaw size large Is the following hypotheses about the samples plausible given your data on jaw sizes in these samples of salamander skulls? Choose True for yes, the hypothesis is plausible. Choose False for no, the hypothesis is not plausible.
