晓岚同学统计了她家5月份的长途电话明细清单，按通话时间画出频数分布直方图，从图中的信息可知，她家通话时间不足10分钟的有多少次？---Chart Description: * **Type:** Frequency Histogram (Bar Chart) * **Main Elements:** * **X-axis:** Labeled "时间/分" (Time/min), representing intervals of time. The intervals shown are 0-5, 5-10, 10-15, 15-20, 20-25. * **Y-axis:** Labeled "频数 (通话次数)" (Frequency (Number of calls)), representing the count within each time interval. The scale ranges from 0 to 30, with major ticks at 5, 10, 15, 20, 25, 30. * **Bars:** Five vertical bars representing the frequency for each time interval: * Interval 0-5 min: Frequency 25. * Interval 5-10 min: Frequency 18. * Interval 10-15 min: Frequency 8. * Interval 15-20 min: Frequency 10. * Interval 20-25 min: Frequency 16. * **Labels:** The frequencies (25, 18, 8, 10, 16) are explicitly labeled above their respective bars. Extraction Content: * **Chart Title:** Implicitly represented by axis labels and context, shows frequency distribution of call times. * **X-axis Label:** 时间/分 (Time/min) * **Y-axis Label:** 频数 (通话次数) (Frequency (Number of calls)) * **Data:** * Time interval 0-5 min: Frequency 25 * Time interval 5-10 min: Frequency 18 * Time interval 10-15 min: Frequency 8 * Time interval 15-20 min: Frequency 10 * Time interval 20-25 min: Frequency 16
