Answer:
The data provide sufficient evidence that older people are more likely to be victimized.
Step-by-step explanation:
H 0 : P = 0.10
H 1 : P > 0.10 (Right tailed test)
n = 527, P = 0.1235
The test statistics
x = P - p / [tex]\sqrt{p*(1-p) / n}[/tex]
x = 0.1235 - 0.10 / [tex]\sqrt{0.10 * 0.90 / 527}[/tex]
x = 0.0235 / [tex]\sqrt{0.09 / 527}[/tex]
x = 0.0235 / [tex]\sqrt{0.00017077798}[/tex]
x = 0.0235 / 0.0130682049264618
x = 1.798257689731729
x = 1.798
P value = [1 - p(Z > 1.7980] (Right tailed test)
P value = 0.036089
The P - Value is very small, so reject H0
Conclusion: The data provide sufficient evidence that older people are more likely to be victimized.
