Suppose 300 randomly selected people are surveyed to determine whether or not they rent their home. Of the 300 surveyed, 60 repo

Vinil7 [7]

Answer: (0.143, 0.257)

Step-by-step explanation:

Given : Level of significance : $1-\alpha:0.99$

Then , significance level : $\alpha: 1-0.99=0.01$

Since , sample size : $n=300$ .

Critical value : $z_{\alpha/2}=2.576$

Also, the proportion of people said that they were fans of the visiting team :-

$\hat{p}=\dfrac{ 60}{300}\approx0.2$

The confidence interval for population proportion is given by :-

$\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$0.2\pm(2.576)\sqrt{\dfrac{0.2(1-0.2)}{329}}\\\\\approx0.2\pm0.057\\\\=(0.2-0.057, 0.2+0.056=(0.143,\ 0.257)$

Hence, the confidence interval for the population proportion with a 99% confidence level= (0.143, 0.257)
