question 63

Multiple Choice

A researcher records the crying time (in minutes) of infants given oral administration of sucrose (n = 12) or tap water (n = 16) prior to a heel prick.The mean crying time in the sucrose group was 3.3±2.4 (M±SD) minutes;in the tap water group,it was 7.3±1.6 (M±SD) minutes.If the null hypothesis is that there is no difference in crying time,then what is the decision for this test?

• A)Crying time was significantly reduced among infants given the water solution prior to a heel prick.
• B)Crying time was not reduced among infants given the sucrose solution prior to a heel prick.
• C)Crying time was significantly reduced among infants given the sucrose solution prior to a heel prick.
• D)Crying time was the same in both groups.
