b the dot plot

1. which display makes it clear that there were no rooms with 1 guest?

choose 1 answer:
(partially visible option: the histogram)

Explanation:

Question 1

A dot plot shows individual data points, so we can easily identify the maximum value (number of guests) by looking at the highest - valued dot. A histogram groups data into intervals, and it's not as straightforward to find the exact maximum number of guests as in a dot plot.

A histogram has bars for different intervals. If there is no bar for the interval corresponding to 1 guest, it clearly shows that there were no rooms with 1 guest. A dot plot would just have no dot at the position representing 1 guest, but the absence is more visually clear in a histogram as there is a gap between the bars (or a non - existent bar) for that interval.

Answer:

B. The dot plot
