Jaden recorded the number of pages read in a 20-minute silent reading sprint in English class. Nine values were recorded: 68, 68, 68, 70, 70, 70, 70, 73, 74. A tenth value x is added and is the smallest value. Quartiles: use the median-of-halves method. What is the largest integer x that would be an outlier by the 1.5×IQR rule?
