Read the passage. Then write a paragraph that explains why the two ecosystems have such different kinds of plants. Use the terms

alex41 [277]

Answer:

Maybe the reason why the ecosystem has many different kinds of plants is because of the soil, or the environment around them. Also, maybe some biotic factors like animals or humans could be the reason. Maybe the humans have planted seeds there, and maybe some abiotic factors like soil could also be the reason why. And maybe the plants that grow there receive a lot of rain, or maybe the limiting factor is the rain, and the type of plants that grow there don't need much water to thrive.

A random sample of 600 voters in a particular city found 102 voters who voted yes on proposition 200. find a 95% confidence inte

nexus9112 [7]

N = 600, the sample size

Because 102 voters said 'Yes' to the proposition, the sample proportion is
$\hat{p} = \frac{102}{600} =0.17 \\
1 - \hat{p} = 1-0.17 = 0.83$

The standard error is
$SE_{p} = \sqrt{ \frac{\hat{p}(1-\hat{p})}{n} } = \sqrt{ \frac{(0.17)(0.83)}{600} } = 0.0153$

The confidence interval is
$\hat{p} \pm z^{*} SE_{p}$

From tables, z* = 1.96 at the 95% confidence level.
Therefore the confidence interval is
$0.17 \pm 1.96(0.0153) = (0.14, 0.20)$

Answer: (0.14, 0.20)
