Answer: 1692
Step-by-step explanation:
Formula to find the sample size :
Given : Confidence level : 
⇒ significance level =
z-value for 90% confidence interval (using z-table)=
Prior estimate of the population proportion (p) of customers who keep up with regular vehicle maintenance is unknown.
Let we take p= 0.5
Margin of error : E= 2%=0.02
Now, the required sample size will be :
Simplify , we get
Hence, the required sample size = 1692

Answer:
<u>The future value of this investment after 10 years is US$ 5,152.58</u>
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Investment = US$ 2,500
Annual interest rate = 7.5% compounded annually
Duration of the investment = 10 years
2. Let's find the future value of this investment after 10 years, using the following formula:
FV = PV * (1 + r) ⁿ
Replacing with the real values, we have:
FV = 2,500 * (1 + 0.075) ¹⁰
FV = 2,500 * 1.0075¹⁰
FV = 2,500 * 2.06103
<u>FV = US$ 5,152.58</u>
