Calculated t= -6.649,P=0.000 which is < 0.05 level. Ho is rejected.
We have enough evidence to conclude that there is significant mean difference between men and women.
95% Confidence interval for mean difference = ( -9.814, -65.346).
The 95% CI does not contains 0 value. There is significant mean difference between the two groups.
