Answer: $4,467.2
Step-by-step explanation:
The formula for this is A = P (1 - r) ^t
Where p is the Principal, r is the rate and t= time
Given from the question, p = $8000
rate= 11% = 11/100 = 0.11
Time = 5 years
Slot the values into the formula:
A= 8000 (1 - 0.11) ^5
= 8000 (0.89)^5
8000 × 0.5584
=$4,467.2
After 5 years, the worth of the car would have depreciated to $4,467.2
I hope this helps.

Step-by-step explanation:
From the question we are told that
The first sample size is 
The first sample mean is 
The first standard is 
The second is 
The second sample mean is 
The second standard deviation is 
The level of significance is 
The null hypothesis is 
The alternative hypothesis is 
Generally the test statistics is mathematically represented as

=> 
=>
Generally degree of freedom is mathematically represented as

=>
