As part of a large,ongoing diet study,some subjects of the study are taking part in an intensive exercise program for four weeks.Several variables are measured on these subjects,both at the beginning and at the end of the four-week period.Some of these variables are weight,cholesterol,and triglyceride level.One objective of this particular study is to assess the effect of diet and intense exercise on increasing triglyceride levels.The data for a simple random sample of nine of these subjects are given in the table below.

Wilcoxon Signed Rank Test

A non-parametric statistical hypothesis test used for comparing two related samples to assess whether their population mean ranks differ.

Null Hypothesis

A default hypothesis that there is no significant effect or difference, serving as the starting point for statistical testing.

Triglyceride Levels

Triglyceride levels measure the amount of triglycerides in the blood, important for assessing heart health and risk for cardiovascular diseases.

Final Answer :
A
Explanation :
The Wilcoxon signed rank test output shows a two-tailed P-value of 0.043, which is less than the typical significance level of 0.05. Therefore, we can reject the null hypothesis that diet and intense exercise have no effect on increasing triglyceride levels, and conclude that there is evidence of a significant increase in triglyceride levels after four weeks of diet and intense exercise.
