Setting up hypothesis tests:Read the following scenarios and write the null and alternative hypothesis for each, then write the conclusion to the hypothesis based on the given results.

1. Researchers at a small engineering firm believe that a new manufacturing process is yielding defective parts. The acceptability rating for their old manufacturing process is 99.99%, but they have observed a rejection rate of 0.2% with the new process. Before reverting to their original manufacturing process, management requests a study to see if the difference is statistically significant, or just a fluke. Before they start the study, the researchers agree to test to a significance level at 0.1.
   1. What is the claim?
   2. What is the null and alternative hypothesis?
   3. Based on their results, the engineers find a p-value of 0.05. Write one or two sentences to discuss the conclusion.
