therefore guided to accept the null hypothesis. The conclusion then is that there is sufficient
evidence to support the claim that there is no difference in means of aggression, thrill, driver
aggression and risk acceptance between genders

values calculated for all the variables except 2 are greater than the set alpha value of 0.05. The
research is therefore guided to accept the null hypothesis. The conclusion then is that there is
sufficient evidence to support the claim that there is no difference in means of driver aggression
and thrill between the modes of studies. However, there was a significant difference in means of
risk acceptance between the modes of studies since the p-value (0.024) is less than 0.05.
