Question

a group of high school students worked part - time jobs over the summer. their weekly earnings are shown in the dot plot. what is the mode of their earnings? $130 $153 $150 $1,530

Explanation:

Step1: Recall the definition of mode

The mode is the value that appears most frequently in a data set.

Step2: Analyze the dot plot

• For $130: 1$ dot (appears 1 time)
• For $140: 2$ dots (appears 2 times)
• For $150: 3$ dots (appears 3 times)
• For $160: 2$ dots (appears 2 times)
• For $170: 1$ dot (appears 1 time)
• For $180: 1$ dot (appears 1 time)

Since $150$ appears the most number of times (3 times) among all the values, the mode is $150$.

Answer:

\$150 (corresponding to the option with text "\$150")
