Answer:

0.60 - 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.570

0.60 + 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.630

The 95% confidence interval for the true proportion would be given by (0.570;0.630) .

And if we convert this into % we got (57.0%, 63.0%)

Step-by-step explanation:

The information given we have the following info given:

n = 1019 represent the sampel size

\hat p=0.6 represent the sample proportion of interest

The confidence level is 95%, our significance level would be given by \alpha=1-0.95=0.05 and \alpha/2 =0.025. And the critical value would be given by:

z_{\alpha/2}=-1.96, z_{1-\alpha/2}=1.96

The confidence interval for the mean is given by the following formula:  

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

Replacing the info given we got:

0.60 - 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.570

0.60 + 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.630

The 95% confidence interval for the true proportion would be given by (0.570;0.630) .

And if we convert this into % we got (57.0%, 63.0%)

Which transformation will carry pentagon EFGHI onto itself?
wariber [46]

Answer:

D

Step-by-step explanation:

The pentagon has 5 interior angles that add up to 360. To find the angle of rotational symmetry, divide 360 by 5 (you get 72). So if you rotated the shape 72 degrees, it will map onto itself. 72 times 2 is 144, and that's rotating the shape 72 degrees twice, so it will stay the same.
