Explanation:

• Symmetrical: A symmetrical histogram has a mirror - image on either side of a central axis. Looking at the given histogram, the left - hand side (e.g., 6 am - 7:59 am, 8 am - 9:59 am) does not mirror the right - hand side (e.g., 8 pm - 9:59 pm, 10 pm - 11:59 pm), so it is not symmetrical.
• Evenly distributed: An evenly distributed histogram has bars of approximately the same height. Here, the bar heights vary significantly (e.g., 4 pm - 6 pm has a much taller bar than 8 am - 9:59 am), so it is not evenly distributed.
• Cluster 4 pm - 10 pm: The bars for 4 pm - 6 pm, 6 pm - 8 pm, and 8 pm - 10 pm are relatively tall compared to other time intervals. Since 4 pm - 10 pm is in the afternoon and evening, this cluster indicates that most texts were sent during this period.
• Texts 6 pm - 8 pm vs 8 pm - 10 pm: By comparing the heights of the bars for 6 pm - 8 pm and 8 pm - 10 pm, the bar for 6 pm - 8 pm is shorter than the bar for 8 pm - 10 pm. So, more texts were not sent from 6 pm - 8 pm than from 8 pm - 10 pm.
• Peak 4 pm - 6 pm: The bar for 4 pm - 6 pm is the tallest among all the bars. In a histogram, the tallest bar (peak) represents the interval with the highest frequency (in this case, the highest number of texts).

Answer:

• The cluster from 4 p.m.–10 p.m. means that most of the texts were sent in the afternoon and evening.
• The peak from 4 p.m.–6 p.m. means that the highest number of texts was sent during this interval.
