Choose the correct answers there is a positive correlation between the size of a hospital (measured by number of beds) and the median number of days that patient remains in the hospital. Does this mean that you can shorten a hospital stay by choosing to go to a small hospital? 1) No – a negative correlation would allow that conclusion, but this correlation is positive. 2) Yes – the data show that stays are shorter in smaller hospitals. 3) No – the positive correlation is probably explained by the fact that seriously ill people go to larger hospitals. 4) Yes – the correlation can’t just be an accident.
