State the H0 (null Hypothesis) and H1 (Claim, Alternative Hypothesis). Identify the claim. Determine whether the test is either left, right or two tailed tests. Show in the sketch of graph. Find the critical value Zα and label on the graph. This is the reject H0 Calculate the test statistic. Make our decision about H0. Interpret the decision. College ABC claims that more than 80% of their graduates find a job within 6 months of graduation. Test this claim if in a random survey of 300 graduates, 250 say that they find jobs 6 months after they graduated with a α = 0.01 Hint: This problem uses proportion.
