Question: A nursing student read that neonates (newborn babies) sleep an average of 18 hours on their first day in the “outside world.” This particular nursing student, who has recently read a book on biostatistics, wondered about the variation about this average. She observed the first day of life for 25 babies in the nursery of a large rural hospital. She obtained the following data (hours spent sleeping). Look at the frequency distribution and estimate the size of the standard deviation. Decide whether to computer s, s², or σ and then compute it. Write a sentence about these data including references to the mean and the standard deviation.
