Identify the appropriate test to use for the following scenario:

There is a common belief that the phases of the moon have a powerful influence on behavior. In fact, the
full-moon effect
has been studied by a number of researchers. It is believed that the full moon negatively affects psychological functioning. To study this, a researcher analyzes the number of emergency admissions to psychiatric hospitals during nights when the moon is full. The researcher then analyzes the number of emergency admissions to the same psychiatric hospitals during nights when the moon is not full. The scores represent the number of admissions to each hospital on a random days throughout the year when the moon was full and a random days throughout the year when the moon was not full.
