Chapter 9, Problem 59SE

Triglycerides Triglycerides are a form of fat found in the body. Using data from NHANES, we looked at whether men have higher triglyceride levels than women.

Report the sample means, and state which group had the higher sample mean triglyceride level. Refer to the Minitab output in figure (A).

Carry out a hypothesis test to determine whether men have a higher mean triglyceride level than women. Refer to the Minitab output provided in figure (A). Output for three different alternative hypotheses is provided—see figures (B), (C), and (D)—and you must choose and state the most appropriate output. Use a significance level of $0.05$.
