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.
The answer to your problem is n=7
1x - 1y = 8
<u>1x + 2y = 2</u>
<u>-3y</u> = <u>6</u>
-3 -3
y = -2
x - (-2) = 8
x + 2 = 8
<u> - 2 - 2</u>
x = 6
(x, y) = (6, -2)
