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 men was 97.1 with a population standard deviation of 0.51 and the mean body temperature for 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

Question

What have you tried?  Did you find the required z-score for the 95% Interval?

I think they only want me to explain because you can't solve this problem

tkhunny · Answer

It is easily solved with the appropriate z-score for a 95% Confidence Interval.  Somewhere around 1.96, maybe?
