State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two- tailed test? a = Ho: H = H1: / Select an answer v The test is a Select an answer v test b.) Identify the Sampling Distribution you will use. What is the value of the test statistic? The best sampling distribution to use is the Select an answer v | distribution. The test statistic (z or t value) is = c.) Find or estimate the P-value for the test. The p-value is = Select an answer d.) Conclude the test. Based on this we will | Select an answer v | the null hypothesis
