Answer 1

$a.~Frequency~polygon.\\ b.~Since~it~is~a~large~data~set~so~set~can~be~divided~into~interval~classes\\ for~easy~visualization~using~a~frequency~table.~For~example:~0-10,10-20,...,90-100.~Hence~for~large~data~set,~frequency~polygon~does~not~perform~well.\\ c.~Display~the~frequency~distribution~of~similarity~values~between~equivalent\\ proteins~in~humans~and~pufferfish~of~the~genus~Fugu.\\ d.~Negatively~skewed~since~the~longer~tail~of~the~distribution~is~\\ towards~the~lower~values~of~the~similarity~(\%).\\ e.~Maximum~frequency~occurs~at~70\%~(see~the~bar~at~70\%~which~is~biggest\\ than~other)~so~mode=70\%.$
