Refer to the sample of body temperatures (degrees Fahrenheit) in the table below. Given these temperatures, what issue can be addressed by conducting a statistical analysis of the data? Subject 2 3 4 5 1 97.0 98.5 97.6 97.7 98.7 8 AM 12 AM 97.6 97.8 98.0 98.4 98.4 Choose the correct answer below. OA. The data can be used to address the issue of whether there is a correlation between body temperatures at 8 AM and at 12 AM. OB. The data can be used to address the issue of whether there is a difference between average body temperature for males and for females. OC. The data can be used to address the issue of whether there is a correlation between average body temperature and a person's exposure to sunlight. OD. The data can be used to find the percentage of people whose body temperature increases with illness. DELL
