12) Please solve for all parts of the question correctly.

For the following hypothesis test, determine the null and alternative hypotheses. Also, classify the hypothesis test as two-tailed, left-tailed, or right-tailed.

The mean length of imprisonment for motor-vehicle theft offenders in this country is 15.2 months. 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 15.2 months.

Choose the correct null and alternative hypotheses below.

A. \( H_0: \mu < 15.2 \, \text{months} \)  
   \( H_a: \mu = 15.2 \, \text{months} \)  

B. \( H_0: \mu = 15.2 \, \text{months} \)  
   \( H_a: \mu > 15.2 \, \text{months} \)  

C. \( H_0: \mu = 15.2 \, \text{months} \)  
   \( H_a: \mu < 15.2 \, \text{months} \)  

D. \( H_0: \mu > 15.2 \, \text{months} \)  
   \( H_a: \mu = 15.2 \, \text{months} \)  

E. \( H_0: \mu = 15.2 \, \text{months} \)  
   \( H_a: \mu \neq 15.2 \, \text{months} \)  

F. \( H_0: \mu \neq 15.2 \, \text{months} \)  
   \( H_a: \mu = 15.2 \, \text{months} \)  

Which of the following is the correct classification of the hypothesis test?

A. Two-tailed  
B. Left-tailed  
C. Right-tailed
