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

normally distributed, calculate the 95% confidence interval 

I think you should first find how many standard deviations above and below the mean
it takes to get 95% of the area of the bell curve.
Do you have a table you can use ?
