Answer:

The third comment is the true one: "If I know the measures of angles C and B, I can find the measures of A and D."

This is because you can use the angle B to find angle A by subtracting it from 180, and you can find angle D by adding together C and B and subtracting that from 180.

I hope this helps!

In a study of 11,000 car crashes, it was found that 5720 of them occurred within 5 miles of home. Use a .05 significance level t

ki77a [65]

Answer:

Claim is true

Step-by-step explanation:

n = 11000

x = 5720

Claim : more than 50% of car crashes occur within 5 miles of home.

$H_0:p=0.5\\H_a:p>0.5$

We will use one sample proportion test

$\widehat{p}=\frac{x}{n}\\\widehat{p}=\frac{5720}{11000}\\\widehat{p}=0.52$

Formula of test statistic = $\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

= $\frac{0.52-0.5}{\sqrt{\frac{0.5(1-0.5)}{11000}}}$

=4.19

Significance level = 0.05

z at 0.05 = 1.64

Since calculated z > defined z

So, null hypothesis is rejected

Hence the claim is true that 50% of car crashes occur within 5 miles of home.
