Data analysis 11
Table 16
From the t-test table results above, it can be observed that the p-values computed are less (0.00)
compared to the level of significance (0.05). This means that the mean aggression, thrill seeking
and risk acceptance scores differ significantly by RTA.
Question four

The anova results show that the computed p-value (0.57) is greater compared to the level of
significance (0.05). This means that the null hypothesis is accepted. It is concluded therefore that
null hypothesis is significant at 95% level of confidence.

Table 21
From the results table above, it can be observed that the value of the coefficient for the living
arrangement is -0.049. This value is close to zero. It is an indication that there is no association
between RTA and living arrangement. To add on, the odds of the predictor variables are tending
towards 1, this is an indication that they cause a great variation in RTA if they are increased.
