I have a sample of 200 their body weight is normally distributed with mean 67kg and sd 20kg 95%CI (64.23, 69.77). the hypothesis is about whether mean is different between males and females, the statistical test i used to test this hypothesis is two-sample t-test. i also have the 95%CI of the estimated mean weight difference (3kg, 14kg). the question is what do you think about the p-value would it be greater or less than 0.05?

how I would know that when a lot of information regarding the two groups are missing???
