12(t + 2) + 4 ≥ - 8
12t + 24 + 4 ≥ - 8
12t + 28       ≥ - 8
12t               ≥ - 8 - 28
12t               ≥ - 36
t                  ≥ - 36 ÷ 12
t                  ≥ - 3
Solution:
t ≥ -3
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for the average using the finite correction factor is:

The information provided is:

The critical value of <em>z</em> for 95% confidence level is,
<em>z</em> = 1.96
Compute the 95% confidence interval for the average number of years until the first major repair as follows:

      
Thus, the 95% confidence interval for the average number of years until the first major repair is (3.1, 3.5).
