Answer:

A statistical question Len could ask is <u><em>"How tall is a red kangaroo?"</em></u>

Step-by-step explanation:

A statistical question is something that we can ask and test hypotheses about using collected data. There will not be a specific answer, but rather multiple answers and we can average them in a sampling distribution.

Let's examine each question:

<u>"How tall is a red kangaroo?"</u>

  • There is not a specific height for each kangaroo, so we can take the averages of many different samples and find the "true mean" in the sampling distribution. This is a good example of a statistical question because data can be collected on red kangaroos and means can be calculated.

<u>"Are there red kangaroos in Asia?"</u>

<u>"Are red kangaroos an endangered species?"</u>

<u>What is the tallest red kangaroo ever recorded?"</u>

  • These are all examples of non-statistical questions. They are "yes" or "no" questions, and we cannot take multiple samples to determine the answer. Rather, there is a single answer that we do not need to test hypotheses or perform any statistical calculations.

mr_godi [17]

Answer:

20%

Step-by-step explanation:

So, I would set this up as a proportion-

72          x

90        100

Cross multiply-

100 x 72 = 7200

Divide-

7200/90 = 80

Subtract-

100 - 80 = 20

So, it is a 20% decrease
