Answer: It will take him 1.68 years to recover his initial investment.
First, find the amount of extra money that he will make.
34,000 - 13,000 = 21,000
He will be making an extra 21,000 per year.
Now, divide the cost of his training by the amount of his increase.
35200 / 21000 = 1.68
That gives you the amount of years it will take him to pay off his investment.
It would be 24 blue cars. ( I can't show the work because my camara is not working)

Using the z-distribution, the confidence interval is given by: (11.95, 12.65).
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:
In which:
- is the sample mean.
- is the standard deviation for the population.
In this problem, we have a 90% confidence level, hence, z is the value of Z that has a p-value of , so the critical value is z = 1.645.
The other parameters are given as follows:
Hence the bounds of the interval are:
