**Sample Size Calculation for Estimating Population Mean**

To determine the minimum sample size required to estimate an unknown population mean (μ), consider the following parameters:

- **Margin of Error (E):** $126
- **Confidence Level:** 99%
- **Standard Deviation (σ):** $500

Given these parameters, calculate the appropriate sample size (\( n \)) using the formula for margin of error in estimating a population mean. The options provided for sample size are:

A. 43  
B. 105  
C. 53  
D. 60  

Make sure to use the z-value corresponding to the 99% confidence level in your calculations.
