A powder diet is tested on 42 people, and a liquid diet is tested on 35 different people. It is of interest whether the liquid diet yields a different mean weight loss than the powder diet. The powder diet group had a mean weight loss of \( \vec{x}_{2}=41.05 \) pounds with a standard deviation of \( 5.10 \) pounds. The liquid diet group had a mean weight loss of \( \bar{x}_{1}=40.14 \) pounds with a standard deviation of \( 2.93 \) pounds. In the past, the standard deviation for weight loss with the powder diet has been \( 4.02 \) pounds and \( 5.1 \) pounds for a liquid diet. Use a \( .05 \) level of significance and perforn a hypothesis test. Round all answers to 4 places where possible. Step (1) Determine the null and altemative hypotheses. Step (2) Determine the test statistic and p-value.
