Question
![There has been a long-held belief that births occur more frequently in the "small hours of
the morning" than at any other time of day. Sutton [1945] collected the time of birth at
the King George V Memorial Hospital, Sydney, for 2654 consecutive births. (Note: The
total number of observations listed is 2650, not 2654 as stated by Sutton.) The frequency
of births by hour in a 24-hour day is listed in Table 3.16.
(a) Sutton states that the data "confirmed the belief ... that more births occur in the
small hours of the morning than at any other time in the 24 hours." Develop a
graphical display that illustrates this point.
(b) Is there evidence of Sutton's statement: "An interesting point emerging was the
relatively small number of births during the meal hours of the staff; this sug-
gested either hastening or holding back of the second stage during meal
hours"?
