Question 4 Fill in the average number of hours each living being sleeps in a day by looking at the charts. Select the appropriate hours from this list : 15, 2.5, 20, 8, 3.5, 13, 10.5, 18.We have a total of 24 hours in a day, represented by the full circles. The blue slice is sleep. Now, let’s match hours 15, 2.5, 20, 8, 3.5, 13, 10.5, 18 from smallest to largest Giraffe: The tiniest sliver, about 10% of the day. This matches 𝟐.𝟓 hours. Elephant: Slightly bigger than the giraffe. This matches 3.5 hours. Human: The blue covers exactly 1/3 of the circle. Since 24/3=8, this is 𝟖 hours. Dog: The blue is just under half the circle. This matches 𝟏𝟎.𝟓 hours. Cat: The blue is just over half the circle. This matches 𝟏𝟑 hours. Squirrel: The blue covers a solid majority, more than half but less than three-quarters. This is 𝟏𝟓 hours. Snake: The blue covers exactly 3/4 of the circle. 3/4 of 24 is 18 . This is 𝟏𝟖 hours. Bat: The largest slice, almost the entire day. This matches 20 hours.
