Select the true
statement(s). Every t distribution is symmetric and centered at 0. The confidence interval for μ based on a t distribution is valid for any underlying distribution. Every t distribution has more variability than does the Z distribution. The confidence interval for μ based on a t distribution is used only for sample sizes less than or equal to 30.
