The p value is known to be greater than 0.05 and therefore the null hypothesis is accepted.
Therefore, there is absence of any difference in the means of thrill, agression and risk
acceptance. From the solution provided in the table it can be concluded that there is absence
of any difference in the means of aggression and risk acceptance between the genders. Here
also P value is above 0.05 which sates there is no difference between the means of the
variable.

The p value is 0.74 which is more than 0.05 states that there is absence of nay diference in
mean in depression between metro stautses
Table 18
The p value is 0.08 which manes that the null hypothesis should be accepted.
