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 different 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. Conduct a hypothesis test at the 5% level of significance. a) State the null and alternative hypotheses in terms of the appropriate parameter. Ho: Select an answer ♥? ♥ pounds Ha: Select an answer ♥? v pounds b) The test statistic is ?v (If necessary, round your answer to the nearest hundredth.) c) The p-value is . (If necessary, round your answer to three decimal places.) d) The correct decision is to Select an answer ♥ the null hypothesis. e) There is Select an answer ♥ evidence at the 5% level of significance that the liquid diet yields a different weight loss than the powder diet.
