Question

number of minutes for each commercial break
the center is 3.
the peak is 5.
there are no gaps.
it is symmetric.
it is skewed right.

Explanation:

Step1: Analyze the center

The data points are 1 (3 times), 3 (7 times), 5 (3 times). To find the center (median), we arrange the data in ascending - order. There are 3 + 7+3 = 13 data points. The median is the 7th value when ordered. Since the first 3 values are 1s and the next 7 values start from 3, the median (center) is 3.

Step2: Analyze the peak

The peak is the value with the highest frequency. The value 3 has a frequency of 7, which is the highest. So the peak is 3, not 5.

Step3: Analyze gaps

There are no data points for 2 and 4, so there are gaps.

Step4: Analyze symmetry

The data is not symmetric. The left - hand side (3 data points for 1) and the right - hand side (3 data points for 5) are not mirror images of each other with respect to the center 3.

Step5: Analyze skewness

Since the tail of the data is on the right (fewer data points on the right side of the peak), it is skewed right.

Answer:

The center is 3.
It is skewed right.
