I think I get it now, but do you think you can help with this one...?

Carla conducted an experiment to determine if the there is a difference in mean body temperature for men and women. She found that the mean body temperature for men in the sample was 97.1 with a population standard deviation of 0.51 and the mean body temperature for women in the sample was 98.2 with a population standard deviation of 0.57.

Assuming the population of body temperatures for men and women is normally distributed, calculate the 95% confidence interval and the margin of error for the mean body temperature for both men and women. Using complete sentences, explain what these confidence intervals mean in the context of the problem.
