Question

compare the shapes, the centers, and the spreads of both classes: the dot plots show the number of miles run per week for two different classes. for 1–5, use the dot plots shown. (dot plots for class a (mi) with axis 0,2,4,6,8,10,12,14 and class b (mi) with same axis) a a. class a is bimodal, class b is bimodal, and class a has a higher spread b a. class a is bimodal, class b is unimodal, and class a has a higher spread c a. class a is unimodal, class b is unimodal, and class a has a higher spread d a. class a is unimodal, class b bimodal, and class a has a lower spread

Explanation:

Step1: Analyze Shape (Modality)

• Class A: The dot plot has two distinct peaks (around 4 and 12), so it's bimodal.
• Class B: The dot plot has one main peak (around 7), so it's unimodal.

Step2: Analyze Spread

• Spread refers to the range (or variability) of data. Class A's data ranges from 4 to 14, while Class B's ranges from 3 to 9. So Class A has a higher spread.

Step3: Match with Options

• Option B states "Class A is bimodal, Class B is unimodal, and Class A has a higher spread", which matches our analysis.

Answer:

B. Class A is bimodal, Class B is unimodal, and Class A has a higher spread
