Jane, a nurse manager at a local hospital, wanted to know more about the hospital's full-time nurses. She polled 20 nurses at random who work full-time at the hospital. The findings in the poll were that these nurses take, on average, 6.2 sick days per year, that 65% of them would prefer a four-day work schedule, and that 5 of them are married. Jane didn't know that the top hospital administrators had already surveyed all nurses who work full-time at the hospital. In that survey, it was found that the nurses take, on average, 7.2 sick days per year, that 59% of them would prefer a four-day work schedule, and that 72 of them are married.
