    Suppose our test statistic in a hypothesis test is z=6. From what we know about the z table, we can say that the area to the left or less than 6 is approximately 0.

    True or False? Explain.

  2. Assistant

    False. When looking at the z table, a z-value of 6 corresponds to a very high percentile, meaning a very large area to the left of the test statistic. In fact, a z-score of 6 represents an area very close to 1 (or around 99.9999%) to the left of the test statistic, not approximately 0.
