Transcribed Image Text:
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. 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.

a. The sample mean for the women was 122.6. (Type an integer or a decimal.)
The sample mean for the men was 122.6. (Type an integer or a decimal.)
Determine which group had the higher sample mean triglyceride level.
The men had the higher sample mean triglyceride level.
b. Determine the hypotheses for this test. Let uw be the population mean triglyceride level for women, and let μm be the population mean triglyceride level for men. Choose the correct answer below.
OA. Ho: HwHm
Ha Hw Hm
OB. Ho: HwHm
Ha: Hw Hm
OE. Ho: Hw Hm
Ha: Hw*μm
OC. Ho: Hw Hm
Ha: Hw Hm
OF. Ho: Hw Hm

OD. Ho: Hw Hm
H₂: Hw Hm
Find the test statistic for this test.
t = (Type an integer or a decimal.)
Find the p-value for this test.
p-value = (Type an integer or a decimal.)
What is the conclusion for this test?
OA. Reject Ho. Men have a significantly higher mean triglyceride level than women.
OB. Reject Ho. Men do not have a significantly higher mean triglyceride level than women.
OC. Do not reject Ho. Men have a significantly higher mean triglyceride level than women.
OD. Do not reject Ho. Men do not have a significantly higher mean triglyceride level than women.
