Answer:

The margin of error is given below:

$E=z \times \sqrt{\frac{\hat{p}(1-\hat{p}}{n} }$

Where:

$\hat{p}=\frac{26}{80}=0.325$

$\therefore E = z \times \sqrt{\frac{0.325(1-0.325}{80} }$

$=z \times 0.0523659$

Therefore, the option E = z*6% is correct as it closest to the given answer

Step-by-step explanation:

Hey there!

According to the question, you need to find out the distance from your friend's house to school.

Firstly figure out the coordinate of your school and school. Then use formula of distance.

So, we find the coordinates as (7,7) and (5,0).

So, x 1 = 7 y1= 7

x 2 = 5 y2 = 0

~ Use distance formula.

$d = \sqrt{( {x2 - x1)}^{2} + ( {y2 - y1)}^{2} }$

~ Put all values.

$d = \sqrt{ {(5 - 7)}^{2} + ( {0 - 7)}^{2} }$

~ Simplify it.

$d = \sqrt{ {( - 2)}^{2} + {( - 7)}^{2} }$

$d = \sqrt{4 + 49}$

$d = \sqrt{53}$

D= 7.280

Therefore, the distance between your friend's house and your school is 7.3 units.

Hope it helps....
