10. 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 3.32.4 (M+SD) minutes; in the tap water group, it was 7.31.6 (M+SD) minutes. If the null hypothesis is that there is no difference in crying time, then what is the decision for this test? (Hint: use CIs) a. b. C. d. Crying time was significantly reduced among infants given the water solution prior to a heel prick. Crying time was not reduced among infants given the sucrose solution prior to a heel prick. Crying time was significantly reduced among infants given the sucrose solution prior to a heel prick. Crying time was the same in both groups.
