Step-by-step explanation:
<u>Part A</u>
Assuming that conditions have been met for the interval, we use the formula
where
represents the sample mean,
represents the critical value,
represents the sample standard deviation, and
is the sample size.
The critical value of
for an 80% confidence level with degrees of freedom
is equivalent to 
Thus, we can compute the confidence interval:

Therefore, we are 80% confident that the true mean age of all customers is between 30.17 and 35.11 years.
<u>Part B</u>
The margin of error is 
Answer:
