Scientists are closely monitoring caribou populations to examine the effect of global climate change on
habitat. The maximum population size for a herd of caribou based on the amount of habitat was 500,000. A
herd of caribou currently has a population size of 198,000 caribou as a result of habitat loss. Which of the
following methods should be used to determine the percent change between the maximum population and
the current population for this herd of caribou?

Respuesta :

Answer: (198,000 caribou - 500,000 caribou) / 500,000 x 100

Explanation: makes sense for the math

The percentage difference allows testing the hypothesis. The decrease of 60.4% of the herd is due to the decrease of the habitat.

To test the scientists' hypothesis between the size of the caribou population and the size of the habitat, they must use a statistical method.

The percentage difference is a method that shows the difference between the current values ​​and some reference ones, it allows knowing the magnitude of the change between the two values, its expression is

            D% =[tex]\frac{measured \ value - reference \ value }{reference \ value } \ 100%[/tex]

Let's calculate

              D% = [tex]\frac{198000 - 500000 }{ 500000}[/tex]198000 - 500000/500000 100

              D% = -60.4%

The negative sign indicates decrease.

Therefore, the percentage difference allows the hypothesis to be tested. The decrease of 60.4% of the caribu is due to the decrease of the habitat.
