SOVA2 [1]

To obtain an estimate of a parameter of a population, we use confidence intervals.

Confidence intervals:

The larger the sample size, the closest the parameter estimate is to the value of the population, as the margin of error of confidence intervals is inversely proportional to the sample size, that is, a greater sample leads to a smaller margin of error.

Thus, you should select the highest sample size in the options.

An ecologist studies the fox population of the arctic circle, and observes that the population loses 1/11 of its size every 7 mo

Ksju [112]

Answer: The fox population decrease 1.298% every month.

Step-by-step explanation:

Since we have given that

Initial foxes = 170000

Every 7 months, the population loses $\dfrac{1}{11}$

So, we need to find the rate of change in population every month.

So, we will use "Unitary method":

So, In every month, the population loses $\dfrac{1}{11}\times \dfrac{1}{7}=\dfrac{1}{77}$

So, the percentage would be

$\dfrac{1}{77}\times 100=1.298\%$

Hence, the fox population decrease 1.298% every month.
