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:
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
So, the value of test statistic would be
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.

<h2>
Answer:</h2>
$52.63
<h2>
Step-by-step explanation:</h2>
To find 20% of $43.86 we multiply $43.86 by 0.2
$43.86 • 0.2 = $8.772
Now add $43.86 and $8.772 to find out how much the family paid altogether.
$43.86 + $8.772 = $52.632
In money the smallest place value is cents so we have to round to the hundredths place.
Doing this we get the grand answer of:
$52.63
