Confidence Interval for µ (σ unknown)

This example demonstrates how to calculate the confidence interval for estimating a population mean (µ) when the population standard deviation (σ) is unknown using GeoGebra. Key mathematical concepts include confidence intervals, t-distribution, sample mean, sample standard deviation, and margin of error. The construction utilizes commands like Segment, Integral, and Textfield, involving objects such as xbar, confidence, n, h, t_α, s, E, μ_L, f, μ_U, g, A, B, a, b, c, C, D, F, G, d, e, inputBox1, inputBox2, inputBox3, inputBox4, text5, text2, text1, text3, text4. Suitable for high school and above students learning statistical inference and confidence interval calculations.
