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.

independent samples t-test was not significant (t [7] = 3.59, p > .05). there was no difference.
an independent samples t-test was significant (t [7] = 3.59, p < .01). 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).

Ответ:
GCF = 4
for the values 8, 12, 20
Step-by-step explanation:
The factors of 8 are: 1, 2, 4, 8
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 20 are: 1, 2, 4, 5, 10, 20
Then the greatest common factor is 4.
