Answer:

Claim is true that most medical malpractice lawsuits are dropped or dismissed.

Step-by-step explanation:

Given :In a study of 799 randomly selected medical malpractice lawsuits, it was found that 499 of them were dropped or dismissed.

To Find : Use a 0.05 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed.

Solution:

n = 799

x = 499

We will use one sample proportion test

$\widehat{p}=\frac{x}{n}\\\widehat{p}=\frac{499 }{ 799}\\\widehat{p}=0.6245$

We are given that the claim is most medical malpractice lawsuits are dropped or dismissed.

Probability of dropped or dismissed is 1/2

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

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

= $\frac{0.6245-0.5}{\sqrt{\frac{0.5(1-0.5)}{799}}}$

= 7.038

p value (z>7.038) is 0

α =0.05

So, p value < α

So, we reject the null hypothesis

So,claim is true

Hence most medical malpractice lawsuits are dropped or dismissed.

20 points helppppppppppppppppppppppppppppp PLZZ anyone solve this ASAP

Sonja [21]

Answer:

$cos^{-1}(cos\frac{ 7π}{6})=cos^{-1}(cos\frac{7*180}{6})$

$cos^{-1}(cos{210})$

$cos^{-}(cos(180+30))$

[since in third quadrant cos 30=- $\frac{\sqrt{3}}{2}]$

$cos^{-}(- \frac{\sqrt{3}}{2})$

:150°or $\frac{5π}{6}$

150°or  $\frac{5π}{6}$ is a required answer.

bongo had a balance of $345.28 in his checking account. During the week amounts: $65.08, $24.50, and $118.95. He then made a dep

vichka [17]

Answer: 192.75

Step-by-step explanation:

I am answering your question assuming that the three amounts were checks that were written out during the week.

Beginning balance = 345.28

Subtract the total amount of the checks (65.08 + 24.50 + 118.95 = 208.53)

345.28 - 208.53 = 136.75

Next, add the amount of the deposit. 136.75 + 56.00 = 192.75
