**Sample Size Determination for Confidence Levels**

**Objective:** Determine the minimum sample size required when the goal is to be 90% confident that the sample mean is within one unit of the population mean. Assume the population is normally distributed, with a standard deviation (σ) of 12.4.

**Task:** Calculate the sample size needed for a 90% confidence level.

**Requirement:** The sample size must be rounded up to the nearest whole number as necessary.

This exercise involves applying statistical methods to ensure accurate representation of the population through sampling, while accounting for confidence levels and variability.
