This is comprised of mean,minimum, maximum as well as standard deviation. It has been gained that mean of gender is .7299. Along with this its standarddeviation is 0.44. On the other hand the mean value of fee status is 0.1011. Further its minimum value is 0 and maximum value is 1.However its standard deviation is 0.374

From the above table it can be interpreted that in all the cases the significance value is above 0.05. Thisimplies that H0 is accepted. This implies that there is no significant mean difference between aggression, thrill seeking and riskacceptance as well as gender.b. Metropolitan background status7
