Which of the following experiments uses independent samples? O You want to test whether a sample of chimpanzees raised in captivity and fed a strict vegan diet for their lifetimes live longer than the known average life span for all chimpanzees living in captivity. O You want to compare the depression levels of teenage girls before and after attending a weeklong camp focused on improving self-image. So you compare the mean Hamilton depression scores of a randomly selected group of teenage girls before and after they attend a weeklong camp focused on improving self-image. O You want to compare the mean first-month weight gain of premature babies to that of full-term babies. So you compare the mean first- month weight gain of a random sample of premature babies to the mean first-month weight gain of a random sample of full-term babies.

known average life span for all chimpanzees living in captivity.
O You want to compare the depression levels of teenage girls before and after attending a weeklong camp focused on improving self-image.
So you compare the mean Hamilton depression scores of a randomly selected group of teenage girls before and after they attend a
weeklong camp focused on improving self-image.
O You want to compare the mean first-month weight gain of premature babies to that of full-term babies. So you compare the mean first-
month weight gain of a random sample of premature babies to the mean first-month weight gain of a random sample of full-term babies.
