Answer:
Option B:


Classification:
The hypothesis test is Two-tailed.
Step-by-step explanation:
The mean length of imprisonment for motor-vehicle theft offenders in this country is 22.1 months.
This means that the null hypothesis is that the mean is of 22.1 months, that is:

A hypothesis test is to be performed to determine whether the mean length of imprisonment for motor-vehicle theft offenders in this city differs from the national mean of 22.1 months.
At the alternate hypothesis, we test if this mean is different of 22.1, that is:

Which means that the answer is given by option b).
Which of the following is the correct classification of the hypothesis test?
We test if the mean is different from a value, which means that the hypothesis test is Two-tailed.
<h2>Answer </h2>
D. 6x>_360; x>_60
<h2>Explanation</h2>
Let
be amount you will save each weeks
Since we know that you are saving over a period of 6 weeks, you will save
.
We also now that your goal is to save at least $360.00 over the period of 6 weeks, so saving more than $360.00 will be very desirable, but the goal is to save $360.00. We can rephrase this as: You need to save $360.00 or more; we can say the same using the inequality symbol
(greater on equal than)
Now we can combine our tow parts using the inequality symbol:

To simplify divide both sides by 6:


You need to save at least $60 per week, so the correct answer is D. 6x>_360; x>_60
