One-Sample T-Test
t = (x̄ - μ) / (s / √n)
When to Use
- Testing if a sample mean differs from a known population mean
- When population standard deviation is unknown
- Sample size is small (though works for any size)
One-sample t-test: determine whether a sample mean differs significantly from a population mean.
