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.
