Answer:

$\frac{1}{6}*\frac{4}{13}$

Step-by-step explanation:

A 6 sided die has 6 outcomes.

Your sister picks from a 13 - slice plate meaning the fact that there are 13 outcomes.

There are 4 yellow slices so picking a yellow slice has a $\frac{4}{13}$ chance

You need to mutiply both displayed values to solve this problem.

$\frac{1}{6}*\frac{4}{13}$

A states division of motor vehicles claims that 60% of teens pass their drivers test on the first attempt. an investigative repo

____ [38]

Answer: There is convincing evidence at the the significance level that the DMV's claim is incorrect.

Step-by-step explanation:

Since we have given that

Hypothesis:

$H_0:p=0.6\\\\H_a:p\neq 0.6$

Probability of teens pass their drivers test on the first attempt = 60% = 0.60

Number of teens = 125

Number of them passed the tests on their first try = 86

$\hat{p}=\dfrac{86}{125}=0.688$

So, the value of test statistic would be

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\z=\dfrac{0.688-0.60}{\sqrt{\dfrac{0.6\times 0.4}{125}}}\\\\z=\dfrac{0.088}{0.0438}\\\\z=2.009\\\\z\approx 2.01$

At α = 0.05% level of significance, critical value = 1.645

Since 1.645 < 2.01

So, we will reject the null hypothesis.

Hence, there is convincing evidence at the the significance level that the DMV's claim is incorrect.

100%-------x (100% is x)

to find x we have too cross multiply

x=100*360/ 24= 1500

hope this helps
