Which expression should you simplify to find the 90% confidence interval,
bogdanovich [222]

Answer:

0.45 - 1.96\sqrt{\frac{0.45(1-0.45)}{36}}=0.2870.45 + 1.96\sqrt{\frac{0.45(1-0.45)}{36}}=0.613

we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613

Step-by-step explanation:

The estimated proportion of interest is \hat p=0.45

We need to find a critical value for the confidence interval using the normla standard distributon. For this case we have 95% of confidence, then the significance level would be given by \alpha=1-0.95=0.05 and \alpha/2 =0.025.

And the critical value is:z_{\alpha/2}=-1.96, z_{1-\alpha/2}=1.96

The confidence interval for the true population proportion is interest is given by this formula:  

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

Replacing the values provided we got:

0.45 - 1.96\sqrt{\frac{0.45(1-0.45)}{36}}=0.287\\\\0.45 + 1.96\sqrt{\frac{0.45(1-0.45)}{36}}=0.613

And we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613

Using transformation (x-2 y+3) find the new coordinates of (7 -5) brainly
trasher [3.6K]

Answer:

(5, -2)

Step-by-step explanation:

In the coordinates (7, -5), 7 is the x-coordinate and -5 is the y-coordinate.

The transformation, (x-2 y+3), states that the x-coordinate, 7, must be subtracted by 2.

When subtracted by two, (7 - 2), the difference is 5.

The transformation, (x-2 y+3), states that the y-coordinate must be increased by 3.

When added by 3, (-5 + 3), the sum is -2.

Therefore, the new coordinates are (5, -2).
