Question 16 of 20 Select the true statement(s). Every t distribution has more variability than does the Z distribution. Every t distribution is symmetric and centered at 0. The confidence interval for u based on a t distribution is used only for sample sizes less than or equal to 30. The confidence interval for μ based on a t distribution is valid for any underlying distribution.
