QUESTION:

The file bodytemp contains normal body temperature readings (degrees Fahrenheit) and heart rates (beats per minute) of 65 males (coded by 1) and 65 females (coded by 2) from Shoemaker (1996). Assuming that the population distributions are normal (an assumption that will be investigated in a later chapter), estimate the means and standard deviations of the males and females. Form 95% confidence intervals for the means. Standard folklore is that the average body temperature is 98.6 degrees Fahrenheit. Does this appear to be the case?

ANSWER:

Step 1 of 5

The data contains the normal body temperature readings and heart beats of 65 males and 65 females. The population follows normal distribution with mean and variance .

The table shows the body temperatures and heart beat rates of males and females. Here 1 represents for males and 2 represents for females.
