Question

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 probl

Answer 1

please help

Answer 2

about all I can contribute is that

95% is 2 standard deviations above and below the mean...

so the range for men is 97.1 - 2*0.51 to 97.1 + 2*0.51

women 98.2 - 2*0.57 to 98.2 + 2*0.57

no idea on the margin of error other than its 1/2 the smallest unit of measurement.

given the standard deviation is calculated to 2 decimal places...it may mean the error is + or - 0.005

but given the mean temps are to 1 decimal place it may mean the error is 0.05

hope its of some help.
