Lynna [10]

The confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.

<h3><u>Confidence interval</u></h3>

To determine what is the 92% confidence interval for the population mean of drivers that do not like driving at night, the following calculation must be performed:

1500 = 100
900 =X
900 x 100 / 1500 = X
60 = X
60 x 0.92 = 55.2
60 x 1.08 = 64.8

Therefore, the confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.

Solve GHI. Round the answer to the nearest hundredth.

Sedaia [141]

Answer:

Part 1) $HI=15\ units$

Part 2)

Part 3) $< I=28.07\°$

The answer is the option A

Step-by-step explanation:

Part 1) Find the measure of side HI

Applying the Pythagoras Theorem

$GI^{2} =GH^{2}+HI^{2}$

substitute the values and solve for HI

$17^{2} =8^{2}+HI^{2}$

$HI^{2}=17^{2}-8^{2}$

$HI^{2}=225$

$HI=15\ units$

Part 2) Find the measure of angle G

In the right triangle GHI

$cos(G)=\frac{GH}{GI}$

substitute the values

$cos(G)=\frac{8}{17}$

$G=arccos(\frac{8}{17})=61.93\°$

Part 3) Find the measure of angle I

Remember that

The sum of the interior angles of a triangle must be equal to 180 degrees

substitute the values

$61.93\°+90\°+< I=180\°$

$< I=180\°-(61.93\°+90\°)=28.07\°$
