Answer:
two-group experiment; independent samples t-test
Explanation:
- A two-group experiment is designed to study the cause-effect relationship between any two variables.
- In a two-group experiment, the researcher conducts a study on two groups - one of which is the control or the placebo group and the other one is the treatment group.
- The study conducted by Juanita also consists of a group of participants of which one is a placebo group and the other is the group that has received adrenaline and hence this is a two-group experiment.
- An independent samples t-test is applied when we need to make a comparison between two groups and thus, see the outcome of the statistical difference between the means of two groups or the two types of interventions used.
- Since this test can be applied by Juanita this would be the most appropriate t-test to be used.
