Hypothesis Test Requirements For all questions involving a hypothesis test, be sure to include all the required steps: 1. State the null (Ho) and alternative (H or HA) hypotheses and identify the claim. 2. Using the sample data, compute the test statistic. 3. Using the level of significance, calculate the critical value. 4. Compute the p-value. 5. Using the test statistic and critical, make a decision: Reject Ho or Fail to reject Ho. Using the p-value and level of significance, make a decision: Reject Ho or Fail to reject Ho. 6. Interpret the results in the context of the original problem. Decision: Reject Ho Decision: Fail to reject Ho Claim: "There is sufficient evidence to warrant rejection of the claim that (original claim)." "There is not sufficient evidence to warrant rejection of the claim that .... (original claim). Ho www Claim: "The sample data support the claim that ... (original claim)." "There is not sufficient sample evidence to support the claim that (original claim). Ha
