Use the sample data and confidence level to construct the confidence interval estimate of the population proportion p. n equals

FrozenT [24]

Answer:

(0.2599,0.3401)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 500

x = 150

$\hat{p} = \dfrac{x}{n} = \dfrac{150}{500} = 0.3$

Confidence interval:

$\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.96$

Putting the values, we get:

$0.3\pm 1.96\sqrt{\dfrac{0.3(1-0.3)}{500}} = 0.3 \pm 0.0401 =(0.2599,0.3401)$

The 95% confidence interval is (0.2599,0.3401).

Need help solving -13 + 2c + 5c + 2

german

Answer:

7c - 11

Step-by-step explanation:

To solve this, you are going to need to add like terms.

Since 5 and 2 both have a "c" next to them, you can add those together to equal 7c.

Then, since -13 and 2 do not have a "c", you can combine those together to equal -7.

Since there is no = , the closest you can get to solving this equation would then be 7c - 11.

Hope this helped!
