Answer:
The problems associated with choosing appropriate sampling units and frame are given below;
Step-by-step explanation:
1. The only aid available to the forester or researcher is a map of the farm.
2. Appropriate sampling units will be hard to choose because farm trees are only characterized by attributes such as
- type of crop/plant (as all trees of a certain crop are much likely to have similar width or diameter)
- height of tree (as height is closely related to width)
- location of tree on the farm (e.g. North on the map, East on the map, South on the map, West on the map)
- age of tree (as older trees are more likely to have diameters exceeding 12 inches, than the younger trees)
- etcetera.
3. Appropriate frame (size) of sample will be hard to choose because a number of trees cannot just be selected from the total number of trees, if the categorization for sampling units is uncertain.
I'm not sure what you mean by "the 3 consecutive numbers of 72".
Do you mean 3 consecutive numbers that ADD UP TO 72 ?
If that's what you want, then you can use this equation:
The middle number . . . . . x
The smallest number . . . . (x-1)
The biggest number . . . . . (x+1)
The equation: (x-1) + (x) + (x+1) = 72 .
Boil that equation down, and you discover that x=24 .
So the 3 numbers are 23, 24, and 25 .
