TEST FOR TWO INDEPENDENT SAMPLES (e) Answer the original question about whether t the difference between each means is real or merely transitory. (n If a difference is real, use Cohen's d to estimate the effect size Answers on pages 438 and 439. test compliance with authority, a classical experiment in social psychology 14.11 To requires subjects to administer increasingly painful electri shocks to seemingly who agonize in an adjacent oom Each subject earns a score helpless victims l tween 0 and 30, depending on the point at which the subject refuses to comply with authority-an investigator dressed in a white lab coat, who orders the administration of increasingly intense shocks. A score of 0 signifies the subject's nwillingness to comply at the very outset, and a score of 30 signifies the subject's willingness to comply completely with the experimenter's orders Ignore the very real ethical issues raised by this type of experiment, and assume that you want to study the effect of a "committee atmosphere" on compliance with authority. In one condition, shocks are administered only after an affirmative decision by the committee, consisting of one real subject and two associates of the investiga- tor, who act as subjects but, in fact, merely go along with the decision of the real subject. In the other condition, shocks are administered only after an affirmative decision by a solitary real subject. A total of 12 subjects are randomly assigned, in equal numbers, to the committee condition (X) and to the solitary condition (X). A compliance score is obtained for each subject. Use t to test the null hypothesis at the .05 level of significance. COMPLIANCE SCORES COMMITTEE SOLITARY 20 15 4 10 10 14 aries nf workshops on creative thinking

Answer 1

Hypotheses are:

$H_{0}:mu_{1}=mu_{2}$

Following is the independent sample t test:

The test statistics is

t = 0.66

The p-value is 0.5222

Since p-value is greater than 0.05 so we fail to reject the null hypothesis.
