A vitamin K shot is given to infants soon after birth. Nurses at Northbay
Healthcare were involved in a study to see if how they handle the infants could reduce the pain the infants feel ("SOCR data nips," 2013). One of the measurements taken was how long, in seconds, the infant cried after being given the shot. A random sample was taken from the group that was given the shot using conventional methods (table #9.3.11), and a random sample was taken from the group that was given the shot where the mother held the infant prior to and during the shot (table #9.3.12). Is there enough evidence to show that infants cried less on average when they are held by their mothers than if held using conventional methods? Test at the 5% level.
