Explain why using the t statistic may be an appropriate alternative to using a z-score

  • stat -

    Usually you use z-tests when sample sizes are large (n is greater than
    or equal to 30) whether or not you know the population standard deviation.

    If you do not know the population standard deviation and have a small
    sample (n < 30), then you can use t-tests.
