Help with margin of error and standard deviation?
Carla wants to determine if there is a difference in the mean body temperature between men and women. She knows that mean body temperature for a sample of 100 men is 97.1 with a population standard deviation of 0.51 and the mean body temperature for a sample of 100 women is 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.
I tried looking at that but it didn't completely click... so I was hoping someone could help me, I've been trying for like an hour, I eventually re-posted the question XD. Thanks anyways though. @HWBUSTER00
