The purpose of the study conducted by Anim-Nyame et al. in 2011 was to examine the ascorbic acid levels in several orange juice products. A random sample of brands were chosen and tested with infusions of reduced or oxidized vitamin C 3 times in two trials. On the right are the results in which researchers believe there may be a difference among the variables. Test the claim at 90% confidence level using the p-value method.questions:1. Identify the independent variables.2. Identify the dependent variable.3. Identify the tail of the test.4. Give the null hypothesis in words.5. Give the alternative hypothesis in words.6. Determine the critical value or p-value ().7. Identify what test to be used.8. Explain why this test is most appropriate.9. Make the decision using specific evidence.10. Summarize the results for the study.
