Ivanna, a nurse manager at a local hospital, wanted to know more about the hospital's full-time nurses. She polled 12 nurses at random who work full-time at the hospital. The findings in the poll were that these nurses take, on average, 5.5 sick days per year, that 50% of them would prefer a four-day work schedule, and that 8 of them are married. Ivanna 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, 5.7 sick days per year, that 61% of them would prefer a four-day work schedule, and that 77 of them are married.
