Psychology and Human Behavior There are many urban legends involving a full moon and human behavior. Research at the University of Basel in Switzerland suggests that sleep is associated with the lunar cycle.56 In a new sleep study, 120 random adults were selected and studied during a full moon phase. Melatonin levels were used to determine whether each person experienced a deep sleep and 76 experienced low levels, and therefore, trouble sleeping, during the full moon. Is there any evidence to suggest that more than half of all people have trouble sleeping during a full moon?

A recent study suggests that Canadians are getting richer but they are among the most indebted people in the world.57 The Bank of Canada suggests that no household should have debt in excess of 160% of annual disposable income. A random sample of 1500 households in Canada’s wealthiest cities, Vancouver, Calgary, and Toronto, was obtained, and 235 were found to be too much in debt. Is there any evidence to suggest that the true proportion of Canadian households that are too much in debt is greater than 14%?
