Greetings!

"How to solve $(-2)^2-(-8)*[(-2)-(-10)]$ "...

Follow PEDMAS:
$(-2)^2-(-8)*[(-2)-(-10)]$
$=(-2)^2-(-8)*[(-2)+(10)]$
$=(-2)^2-(-8)*(8)$
$=4-(-8)*(8)$
$=4-(-64)$
$=4+64$
$=68$

The answer would be 68.

Hope this helps.

A police officer claims that the proportion of accidents that occur in the daytime (versus nighttime) at a certain intersection

Roman55 [17]

Answer: -1.78

Step-by-step explanation:

As per given description, we have

Population proportion : $p=0.35$

Sample size : n= 500

Sample proportion : $\hat{p}=\dfrac{156}{500}=0.312$

Test statistic for population proportion :-

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\\\=\dfrac{0.312-0.35}{\sqrt{\dfrac{0.35(1-0.35)}{500}}}\\\\=-1.78146747757\ \ \text{(Simplified)}\\\\\approx-1.78$

Hence, the test statistic for this hypothesis test for a proportion= -1.78
