In an imaginary survey, we wanted to find out if there is a connection between morning sickness and sleeping position. A random sample of 400 people was selected for the survey. The respondent had to define himself as either a morning person or a non-morning person and tell the position in which he typically sleeps. 186 respondents classified themselves as morning timers and 214 respondents as non-morning timers. Of the morning owls, 127 reported that they usually sleep on their side, 24 on their stomach and 35 on their back.
