Answer:
No, the mode is not in the interval 11-15. There are 10 peoples in the interval 6-10.
Explanation:
The mode is number which occurs most frequently in the data set.
In a histogram, the height peak of the histogram represents the mode of the data.
From the given figure it is noticed that the number of peoples in the intervals 1-5,6-10,11-15 and 16-20 are 5, 10, 5 and 5 respectively. The number of people in the 6-10 is 10.
Since the height peak of histogram is 10 in the interval 6-10, therefore the mode of the histogram is in the interval 6-10.
So, we can conclude that the mode is not in the interval 11-15. There are 10 peoples in the interval.
