Resumo de Recurso

Hypothesis Test
  1. What is the sample size?
    1. n≥30 OR np≥5 nq≥5
      1. Use z-distribution to find your critical value.
      2. n<30 OR np<5 OR nq<5
        1. Do you know the population standard deviation (σ)?
          1. Yes. Use z-distribution to find your critical value.
            1. No. Use t-distribution to find your critical value.
              1. Find the value of the test statistic using the appropriate formula
                1. Compare the critical value and the test statistic. Does the test statistic fall in the rejection region?
                  1. Yes. Since the test statistic falls in the rejection region, there is sufficient evidence to reject the null hypothesis.
                    1. No. Since the test statistic does not fall in the rejection region, there is insufficient evidence to reject the null hypothesis.
                    2. Compare alpha (α) and p-value. Is your p-value less than alpha?
                      1. Yes. Since the p-value is less than alpha, there is sufficient evidence to reject the null hypothesis.
                        1. No. Since the p-value is larger than alpha, there is insufficient evidence to reject the null hypothesis.
