The table gives the types and measurements, in feet, for 20 trees that were nominated for the Big Tree Contest in a certain county. Circumference is the distance around the trunk of a tree measured 4.5 feet above the ground; height is the vertical distance from the ground to the top of the tree; and spread is the distance from the ends of the branches on one side of the tree through the trunk to the ends of the branches on the other side of the tree at the horizontal level where that distance is greatest.
For each statement, select Yes if the information given indicates it is true for the trees in the table. Otherwise, select No.

The table gives the types and measurements, in feet, for 20 trees that were nominated for the Big Tree Contest in a certain county. Circumference is the distance around the trunk of a tree measured 4.5 feet above the ground; height is the vertical distance from the ground to the top of the tree; and spread is the distance from the ends of the branches on one side of the tree through the trunk to the ends of the branches on the other side of the tree at the horizontal level where that distance is greatest.
For each statement, select Yes if the information given indicates it is true for the trees in the table. Otherwise, select No.
Trunk circumference is directly proportional to height.
"Directly proportional" means "increasing together in a constant ratio."
So, if trunk circumference is directly proportional to height, as circumference increases, height will increase, and for each tree, the two will be in about the same ratio.
To check to see whether this choice is supported, we can sort by Circumference. Then, we can check to see whether height increases along with circumference.
Sorting by Circumference, we see that height does not increase along with circumference.
For example, for Fir, Douglas, circumference is 8.17, and height is 80. Then, for Alder, European, circumference is higher, at 9, but height is lower, at 70.
Checking more trees to confirm, we see that height definitely does not increase with circumference. So, we don't even have to bother checking to see whether circumference and height are in a constant ratio to determine that circumference is NOT directly proportional to height.
Select No.
The mode height is 102 feet.
To determine whether this statement is supported, sort by Height.
Having done so, we find the trees with a height of 102 and count 3 such trees.
Now, we scan the height column to see whether any other height is had by 3 or more trees. Doing so, we see that the maximum another number shows up is twice, in the cases of 79 and 85.
So, 102 is the mode.
Select Yes.
If a tree is chosen at random from the 20 trees in the table, the likelihood that it will have a circumference less than 10 feet is 0.20.
To determine the likelihood that a tree randomly selected will have a circumference less than 10 feet, we need to determine what percentage of the trees have circumferences less than 10 feet.
To do so, sort by Circumference.
Now, count the trees with circumferences less than 10 feet. We see that there are 4 such trees.
4/20 = 0.20.
So, the data support this statement.
Select Yes.
