Question

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	8 am	12 am
2	98.5	97.8
3	97.6	98.0
4	97.7	98.4
5	98.7	98.4

choose the correct answer below.
a. the data can be used to address the issue of whether there is a difference between average body temperature for males and for females.
b. 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.
c. the data can be used to find the percentage of people whose body temperature increases with illness.
d. 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.

Explanation:

• Option A: The data has no information about gender (males/females), so it can't address this.
• Option B: The data has body temperatures at 8 AM and 12 AM for the same subjects. We can analyze the relationship (correlation) between these two sets of temperatures.
• Option C: The data has no information about illness, so it can't find the percentage related to illness.
• Option D: The data has no information about sunlight exposure, so it can't address this.

Answer:

B. 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.
