Data was collected at a tennis court. It showed that being older implies that a player will stay for a shorter length of time. What is likely true?There is no correlation between age and length of stay.There is a correlation between age and length of stay. There may or may not be causation. Further studies would have to be done to determine this.There is a correlation between age and length of stay. However, there is no causation. This is because there is a decrease in the length of stay with an increase in age.

This is because there is a decrease in the purchase price with a decrease in age.(b)A doctor's office found that a lower outside temperature did not indicate a change in the number of appointments made. What can we determine from this information?There is no correlation between outside temperature and number of appointments made.There is a correlation between outside temperature and number of appointments made. However, there is no causation. This is because there is likely an increase in the number of appointments made with a decrease in the temperature outside.There is a correlation between outside temperature and number of appointments made. There may or may not be causation. Further studies would have to be done to determine this.(c)A piano instructor examined student progress.
