Abalone are colorful shell fish found throughout the world. When an abalone shell is found, it can be classified as either Male $($M$),$ Female $($F$),$ or Infant $($I$).$ Collectors can usually guess if an abalone is M$,$ F$,$ or I based upon measurements taken of the shell.

Assume that a collector finds an abalone shell with the following measurements in centimeters.

LENGTH $=15$

DIAMETER $($DIAM$)=9$

HEIGHT $=3\mathrm{.}2$

Assume a collector has the following decision tree, is the abalone Male $($M$),$ Female $($F$),$ or Infant $($I$)?$
