Answer :
To solve this question, we need to determine which of the provided options correctly identifies a statistical issue that can be addressed using the given body temperature data.
Let's go through each option:
A. The data can be used to find the percentage of people whose body temperature increases with illness.
- We are not given any information about the subjects being ill or healthy. The data consists of temperatures at different times, and without specific information on illness, we can't address this issue.
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.
- We have body temperature readings for the same subjects at two different times: 8 AM and 12 AM. This option is appropriate because we have the data needed to check if there is a relationship or correlation between these two sets of readings.
C. 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.
- The data provided doesn't include any information about exposure to sunlight, so we can't use this data to explore this issue.
D. The data can be used to address the issue of whether there is a difference between average body temperature for males and for females.
- The data does not specify the gender of the subjects; hence, we cannot address this issue with the information provided.
Therefore, the correct answer is 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. This is because the dataset includes temperature readings at those specific times for the subjects.
