Question

the parallel dotplots below display the number of absences for students in each of two classes. which of the following statements is true? the range for the distribution of the number of absences is larger for class d. the range for the distribution of the number of absences is larger for class c. the iqr for the distribution of the number of absences is larger for class d. the iqr for the distribution of the number of absences is larger for class c.

Explanation:

Step1: Calculate range

Range = maximum - minimum.
For class D: maximum is 5, minimum is 0. Range = \(5 - 0=5\).
For class C: maximum is 10, minimum is 0. Range = \(10 - 0 = 10\). So range is larger for class C.

Step2: Analyze IQR

IQR (Inter - Quartile Range) is based on the spread of the middle 50% of the data. Looking at the dot - plots, the data for class D is more concentrated (less spread in the middle 50% compared to class C).

Answer:

The range for the distribution of the number of absences is larger for class C.
