The mean crying time of infants during naptime at a local preschool is 12 min. The school implements a new naptime routine in a sample of 25 infants and records an average crying time of 8±4.6 (M±SD) min. Test whether this new naptime routine reduced crying time at a .05 level of significance.
A. The new naptime routine significantly reduced crying time, t(24) = –4.35, p < .05. B. The new naptime routine did not reduce crying time, t(24) = –4.35, p < .05. C. The new naptime routine did not reduce crying time, t(24) = 8.67, p > .05. D. The new naptime routine significantly reduced crying time, t(24) = 8.67, p < .05
