Triglycerides are a form of fat found in the body. Using data from a certain organization, determine whether men have higher triglyceride levels than women. a. Report the sample means and state which group had the higher sample mean triglyceride level. Refer to the Minitab output in figure (A). b. Carry out a hypothesis test to determine whether men have a higher mean triglyceride level than women. Assume that all necessary conditions for carrying out a hypothesis test hold. 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. i Click the icon to view the Minitab outputs. a. The sample mean for the women was | |. (Type an integer or a decimal.) The sample mean for the men was ]. (Type an integer or a decimal.) Determine which group had the higher sample mean triglyceride level. The had the higher sample mean triglyceride level. b. Determine the hypotheses for this test. Let , be the population mean triglyceride level for women, and let um be the population mean triglyceride level for men. Choose the correct answer below. O A. Ho: Hw = Hm O B. Ho- Hw Hm O C. Ho- How # Hm Ha : Hw Hm Ha- Hw = Hm Ha- Hw = Hm OD. Ho: Hw = Hm OE. Ho- Hw Hm OF. Ho- How = Hm Ha: Hw # Hm Ha : Hw = Hm Ha- Hw Hm Find the test statistic for this test. 1=(Type an integer or a decimal.) Find the p-value for this test.- X Minitab Output (A) Two-sample T-Test and Cl: Triglycerides, Gender Gender N Mean StDev SE Mean Female 42 80.4 50.4 7.8 Male 44 115.5 62.3 9.4 Difference = mu (Female) - mu (Male) Estimate for difference: - 35.1 95% Cl for difference: ( - 59.4, - 10.8) B: T-Test of difference = 0 (vs ): T-Value = -2.88 P-value =0.997 D D: T-Test of difference = 0 (vs # ): T-Value = -2.88 P-value =0.005 Print Done
