The class interval with 30\% of the data falls between the 40th percentile and the 70th percentile. According to the cumulative percentage column, the class interval with 40\% of the data is 20.5-40.5, and the class interval with 70\% of the data is 40.5-60.5. Therefore, the class interval with 30\% of the data must fall between these two intervals, which is 40.5-60.5.
