In a study of preferences in leafcutter ants, a researcher presented 20 randomly chosen ant colonies with leaves from the two most common tree species in the surrounding forest. The leaves were placed in piles of 100, one pile for each tree species, close to colony entrances. Leaves were cut so that each was small enough to be carried by a single ant. After 24 hours, the researcher returned and counted the number of leaves remaining of the original 100 of each species. Some of the results are show in the following table: Tree Species Number of Leaves Removed Spondius mombin   1561 Sapium thelocarpum   851 Total 2412 Can you answer question regarding to this graph please

Question

In a study of preferences in leafcutter ants, a researcher presented 20 randomly chosen ant colonies with leaves from the two most common tree species in the surrounding forest. The leaves were placed in piles of 100, one pile for each tree species, close to colony entrances. Leaves were cut so that each was small enough to be carried by a single ant. After 24 hours, the researcher returned and counted the number of leaves remaining of the original 100 of each species. Some of the results are show in the following table:


Tree Species

Number of Leaves Removed

Spondius mombin

 

1561

Sapium thelocarpum

 

851

Total

2412

Can you answer question regarding to this graph please 

Do the 2412 leaves represent a random sample?
No, because leaves in the same pile at the same ant colony are not independent.
Yes, because leaves in the same pile at the same ant colony are independent.
Yes, because the ant colonies were randomly selected.
Transcribed Image Text:Do the 2412 leaves represent a random sample? No, because leaves in the same pile at the same ant colony are not independent. Yes, because leaves in the same pile at the same ant colony are independent. Yes, because the ant colonies were randomly selected.
