In a controlled experiment focusing on the effects of dietary changes on cholesterol levels, two researchers, Dr. White and Dr. Black, proposed different hypotheses. Dr. White hypothesized that increasing dietary fiber would lead to a significant reduction in LDL (low-density lipoprotein) cholesterol levels, while Dr. Black suggested that saturated fats in the diet have a more pronounced effect on elevating LDL cholesterol levels.
After conducting their studies, both researchers collected data on LDL levels among participants who followed their respective diets over a period of six weeks. They then analyzed the results to determine which dietary factor had a more significant impact on cholesterol levels.
Based on the hypotheses and subsequent research results, which statement best describes the comparison of their hypotheses?
