Step-by-step explanation:
y is the height of the balloon. x is the time in seconds.
The balloon starts on the ground, so the smallest value of y is 0. We know the rope is 200 feet long, so the biggest value of y is 200. So the range is 0 ≤ y ≤ 200.
Find the value of x at each end of the range.
When y = 0:
0 = 4x
x = 0
When y = 200:
200 = 4x
x = 50
So the domain is 0 ≤ x ≤ 50.
The x and y-intercept is (0, 0). This means the balloon is initially on the ground.

Step-by-step explanation:
Not sure what precision level this problem is looking for, but for right-skewed distributions, we know that the mean is going to be pulled right and therefore the mean should be larger than the median. To a high confidence level, the mean should fall between 50 and 59, or in the third column.
If a single estimation is wanted, assume the values inside each column are uniformly distributed:
