Section A
1. Do states in the south have a higher crime rate?
The above chart shows that maximum participants accept that states have not a higher crime rate.
H0 = There is no significance difference between crime rates
H1 = There is significance difference between crime rates
Independent t-test
One-Sample Test
Test Value = 0
t df Sig. (2-tailed) Mean Difference 95% Confidence Interval of the
Difference

Lower Upper
Southern state 4.873 46 .000 .340 .20 .48
The result indicates the value of t is 4.873, this indicates that there is no significance difference
between crime rate and Southern region.
2. Is there a relationship between crime rate and police expenditure?
The above result has significance value 0.012, which is lower than 0.05 acceptance level. Thus,
there is significance difference between both crime rate and police expenditure. This concludes
that police expenditure have direct impact on crime rate.
Correlation
The above result shows the correlation value 0.646. This indicates there is positive moderately
strong correlation between both variables. R(47) = 0.65, p < 0.01; hence null hypothesis rejected
at 95% significance level and thus there is significance difference between crime rates.
3. Have crime rates increased in 10 years ?
