A population of 55 foxes in a wildlife preserve doubles in size every 14 years. The function y equals 55 times 2 Superscript x ​
Pavlova-9 [17]
Since <em>x</em> is the number of 14-year periods, the first thing we do is divide 28 years by 14. 28/14=2.  Now we use that in our function, y=55*2^x.

y=55*2^2=55*4=220
There will be 220 foxes after 28 years.

Alex787 [66]

Answer:    (4.24,\ 5.36 )

Step-by-step explanation:

The  confidence interval to estimate the population mean is given by :_

\overline{x}\ \pm\ z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Sample size : n= 60 , the sample is a large sample (n>30), so we can apply z-test.

Sample mean = \overline{x}=4.8

Standard deviation : \sigma=2.2

Level of confidence:1-\alpha=0.95

\Rightarrow\ \alpha=0.05

Then, critical z-value =z_{\alpha/2}=1.96

Then, a 95% confidence interval estimate of the population mean will be

=4.8\ \pm\ (1.96)\dfrac{2.2}{\sqrt{60}}\\\\=4.8\pm0.56=(4.8-11.76, 4.8+11.76)=(4.24,\ 5.36 )

Hence, the  95% confidence interval to estimate the population mean = (4.24,\ 5.36 ).
