Question

An experimenter randomly divided a group of volunteers into two groups.   One group fasted for 24 hours and the other for 48 hours. Scores below represent the number of ounces of nutrition consumed during the first 10 minutes after the fast. Was there a difference in the amount of nutrition needed after the fast between the two groups? Select the correct test, perform the test, and interpret the results.

24 hour	48 hour
26	18
35	24
23	16
30	17
	14

		An independent samples t-test was significant (t [5] = 3.45, p < .05). Those who fasted for 48 hours needed less nutrition than those who fasted for 24 hours.
		A paired samples t-test was significant, ( t [3] = 7.08, p < .01). Those who fasted for 48 hours needed less nutrition than those who fasted for 24 hours.
		A Pearson's product moment correlation r shows a relationship (r [7] = .86, p < .05).
		Independent samples t-test was not significant (t [5] = 3.45, p > .05). There was no difference.
