An experiment was performed to compare the quantity of oleoresin derivable from a unit weight of ginger obtained from five countries. Five students with differing skills were given a unit weight of ginger from each of the five countries to determine the oleoresin contents in milligrams.  Analyze the data and compare the mean oleoresin contents of the five gingers at 1% level of significance. Use Duncan’s multiple range test in a post ANOVA analysis to group the ginger means.
