The border of a susan
1 answer:
Actually, the coin is round but it does contain an 11 sided polygon inscribed within the circle.
An eleven sided polygon is called a <span>hendecagon </span><span> (from the Greek </span>hendeka<span> "eleven"</span><span>)
EACH interior angle measures (180 degrees -(360 / number of sides)) =
</span>180 degrees -(360 / 11) =
180 degrees - <span> <span> <span> 32.7272727273 </span> =
</span></span> <span> <span> <span> 147.2727272727 </span> </span> </span>degrees
rounded to nearest degree = 147 degrees

Answer:
The correct option is (e).
Step-by-step explanation:
In this case we need to determine whether there is any difference between the proportion of bats with a wingspan greater than 10 inches living outside the region from that of the bats living in the region.
The hypothesis can be defined as follows:
<em>H₀</em>: There is no difference between the proportion of bats with a wingspan greater than 10 inches living outside the region and of the bats living in the region, i.e. <em>p</em> - <em>p₀</em> = 0.
<em>Hₐ</em>: There is a difference between the proportion of bats with a wingspan greater than 10 inches living outside the region and of the bats living in the region, i.e. <em>p</em> - <em>p₀</em> ≠ 0.
The information provided is:
<em>n</em> = 80
<em>X</em> = 20
<em>p₀</em> = 0.30
A <em>z</em>-test for single proportion will be used to perform the analysis.
Compute the sample proportion of bats living outside of the region having a wingspan greater than 10 inches as follows:
The test statistic is given as follows:
Compute the value of the test statistic as follows:
Thus, the test statistic is .
The correct option is (e).
