Explanation:
The length of each of the 8 commercials that aired was:
92 seconds, 91 seconds, 91 seconds, 93 seconds,
93 seconds, 92 seconds, 91 seconds, 87 seconds.
The mode is the number that appears the most.
First, we arrange the lengths in ascending order.
87 seconds, 91 seconds, 91 seconds, 91 seconds,
92 seconds, 92 seconds, 93 seconds, 93 seconds.
We see that:
• 87 appears 1 time
,• 91 appears 3 times
,• 92 appears 2 times
,• 93 appears 2 times
The number that appears most is 91.
Therefore:
Mode = 91 seconds
