A psychologist wants to determine the effect of an antidepressant drug on the capacity of reaction when facing a danger situation. After conducting a literature review,
she finds enough evidence to formulate her hypothesis in the following way:
H0 : μ1 = μ2 (The drug has no effect on reaction capacity)
H1 : μ1 ≠ μ2 (The drug affects reaction capacity)
She proceeds to select two samples of 10 participants each. One group (X1) was termed "experimental" and the other (X2) "control". The normal dose of the drug was
administered to the first group, and a placebo was administered to the second group. After a reasonable amount of time, the psychologist determined the seconds each
group took to react and obtained the following data:
X1 (Exp) X2 (Control)
20 12
18 10
14 14
20 8
19 13
11 8
8 6
12 6
15 13
13 10
In this problem, you will determine what the psychologist should conclude.
Using the 5% level of significance (alpha):
a) Determine the null and research hypotheses;
b) Select the correct template (templates for the Single Sample t-test, the Independent Samples t-test, and the ANOVA are included in the tabs that follow this tab);
c) Complete each of the blank cells in the template selected.
