conclude that males were more likely to choose Aggressive/Retribution Justification Choices
than females. See Table 25.

CBVS Test and Confidence Interval for the Proportion of Males and the Proportion of Females
who Selected Aggressive/Retribution Justification Choices
Sample ƒ n Sample p

Test of p = 0 vs. p ≠ 0
27 348 0.077586
Difference = p (male) – p (female)
Estimate for difference: 0.0949490
95% CI (0.0427848, 0.147113)
Test for difference = 0 (vs. ≠ 0): Z = 3.57 P-Value = 0.000
Fisher's exact test: P-Value = 0.000
N = 632 responses
A test for the Difference in Proportions tested the following null hypothesis: There is no
difference between the proportion of males and the proportion of females who choose
Justice/Fair Justifications.
Of the 284 Best Justification Choice responses selected by males, 153 were Justice/Fair
Justification Choices (sample p = 0.538732). Of the 348 Best Justification Choice responses
selected by females, 216 were Justice/Fair Justification Choices (sample p = 0.620690). The
estimate of the difference between male responses and female responses was -0.0129917. The
hypothesized difference in proportions of zero does not lie within the 95% CI (-0.159159, -
0.00475523) for the difference in proportions between male responses and female responses to
Justice/Fair Justification Choices. Therefore, zero is not a plausible value for the difference in
proportions between male responses and female responses to Justice/Fair Justification Choices.
