Babies that are born prematurely often have medical problems that require them to spend a long time in the hospital. The more premature a baby is, the less it weighs. BYU--I student Brock Shackett investigated whether a baby's birth weight could be used to predict how long the baby would need to stay in the hospital. Which of the following hypothesis tests would be most appropriate for answering Brock's question?

Options:

	Paired data test
	Independent samples test
	ANOVA
	Test of two proportions
	Chi-squared test of independence
	Hypothesis test for regression
