Question

1. which display can be used to find that there were 2 rooms without guests? choose 1 answer: the histogram the dot plot (with a dot plot image showing number of guests in each room from 0 to 24 with dots above the number line)

Explanation:

A dot plot shows individual data points (dots) for each value on a number line. To find rooms with 0 guests (no dots at 0), we check the dot plot. A histogram groups data into intervals, so it's harder to see individual 0 - value cases. The dot plot clearly displays each room's guest count, so we can identify 2 rooms with 0 guests (no dots at 0, or count the absence).

Answer:

The dot plot
