Answer:

8.4 (42/5)

well you know that 1/4 as a decimal is .25 so take the 5 and put it in front of the .25, so you will have 5.25. And 5/8 as a decimal is .625. then just divide them by using long division or a calculator.

<h2>Answer with explanation:</h2>

The confidence interval for population mean is given by :-

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

, where \hat{p} is the sample proportion, n is the sample size , z_{\alpha/2} is the critical z-value.

The  values needed to calculate a confidence interval at the 99% confidence level are :

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

Sample size : n=450

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

Sample proportion: \hat{p}=\dfrac{280}{450}\approx0.62

Now, the  99% confidence level will be :

\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.62\pm(2.576)\sqrt{\dfrac{0.62(1-0.62)}{450}}\\\\\approx0.62\pm0.023\\\\=(0.62-0.023,\ 0.62+0.023)=(0.597,\ 0.643)

Hence, the  99% confidence interval is (0.597,\ 0.643)
