Ulleksa [173]
<span>If Priya makes 20% more than James and Siobhan makes 15% less than Priya, then it follows that Priya makes 85% of 120% of James' hourly wage. Which is to say that Siobhan makes 85% of $9.60 per hour. Since 85% of $9.60 is $8.16, this means that Siobhan makes $8.16 an hour.</span>

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).
