Question

what is true of the data in the dot plot? check all that apply.
number of minutes for each commercial break
the center is 3.
the peak is 5.
there are no gaps.

Explanation:

Step1: Analyze the center

The center (median) of the data set. First, find the total number of data points. There are \(3 + 10+3=16\) data points. The median is the average of the 8th and 9th data points. Counting the dots: the first 3 are at 1, then 10 at 3. The 8th and 9th data points are both 3. So the center (median) is 3.

Step2: Analyze the peak

The peak is the value with the most dots. The value 3 has 10 dots, which is more than 1 (3 dots) and 5 (3 dots). So the peak is not 5.

Step3: Analyze the gaps

A gap is a value with no dots. The value 2 and 4 have no dots. So there are gaps.

Answer:

The center is 3.
