Question

where is the gap in the data?
number of patients per hour who waited longer than 15 minutes
0
2
4
8

Explanation:

Step1: Analyze the dot plot

The dot plot shows the number of patients per hour who waited longer than 15 minutes. The x - axis values are 0, 1, 2, 3, 4, 5. We check the presence of dots for each x - value. For x = 0, there are multiple dots; for x = 1, multiple dots; for x = 2, one dot; for x = 3, multiple dots; for x = 5, multiple dots. For x = 4, there are no dots.

Step2: Identify the gap

A gap in a dot plot is a value on the x - axis with no corresponding data points (dots). Since there are no dots at x = 4, the gap is at 4.

Answer:

4 (the option corresponding to 4)
