So this question was saying that a powder diet is tested on 49 people and a liquid diet is tested on 36 different people. Of interest is whether the liquid diet yields a higher average weight loss than the powder diet. The powder diet group had an average weight loss of 42 pounds with a standard deviation of 12 pounds. The liquid diet group had an average weight loss of 45 pounds with a standard deviation of 14 pounds. Use ? = .05

5. A powder diet is tested on 49 people and a liquid diet is tested on 36 different people. Of interest is whether the liquid diet yields a higher average weight loss than the powder diet. The powder diet group had an average weight loss of 42 pounds with a standard deviation of 12 pounds. The liquid diet group had an average weight loss of 45 pounds with a standard deviation of 14 pounds. Use a = .05 a. Mean OR Proportion problem? b. Is this a one sample problem OR a two sample problem? c. Explain how the assumptions [or requirements) are met. d. Appropriate parameters : For Proportion problems: provide 15 , x and n For Means problems: provide f, n and Sx (whether one or two samples) e. Hypotheses H0: H1: f. Run the test: t or z stat: p-value = g. Conclusion: h. Interpret the conclusion
