A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than ex

Pachacha [2.7K]

Answer: B. 0.59 plus or minus 0.090

Step-by-step explanation:

The confidence interval of population proportion is given by :-

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

Given : Sample size : $n=200$

The proportion of students are receiving financial aid : $hat{p}=\dfrac{118}{200}=0.59$

Significance level : $\alpha: 1-0.99=0.01$

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

Then, the confidence interval of population proportion is given by :-

$0.59\pm (2.576)\sqrt{\dfrac{0.59(1-0.59)}{200}}\\\\=0.59\pm0.0895877841673\\\\\approx0.59\pm0.090$

Hence, a 99% confidence interval to estimate the true proportion of students on financial aid = 0.59 plus or minus 0.090
