Transylvania Hypothesis The "Transylvania hypothesis" claims that the full moon has an effect on health-related behav- ior. A study investigating this effect found a significant relation- ship between the phase of the moon and the number of general practice consultations nationwide, given by y = 100 + 1.8 cos 14.77 where y is the number of consultations as a percentage of the daily mean and t is the days since the last full moon. Source: Family Practice. (a) What is the period of this function? What is the significance of this period? (b) There was a full moon on October 8, 2014. On what day in October 2014 does this formula predict the maximum number of consultations? What percent increase would be predicted for that day? (c) What does the formula predict for October 25, 2014?
