Flora is a marine biologist working in Thailand. She is currently researching the eating habits of turtles. She believes that the species (A or B) and the gender (M or F) of the turtle may affect its eating habits, measured in ounces of kelp consumed weekly. Flora believes that mean amount of kelp consumed by Species A is less than the mean amount of kelp consumed by Species B. What are the appropriate hypotheses to test her belief?

a. HA: ?A=?B
b. HA: ?A??B
c. H0: ?A=0
d. HA: ?A<?B
e. H0: pA=pB
f. H0: ?A=?B
g. HA: ?A<0
h. H0: pA?pB
