Severаl physiciаns hаve repоrted that patients whо cоnsume apple cider vinegar appear to have lower levels of LDL ("bad" cholesterol) than those who do not consume apple cider vinegar. As a result of this observation, researchers decide to enlist 500 participants, all of which are 65 years of age. Of these participants, 250 are given a specific brand of apple cider vinegar and asked to consume 25 mL every day. The other participants are asked to not consume any apple cider vinegar. After 6 months, researchers measure the participants' LDL levels. Formulate an appropriate scientific hypothesis for the scenario presented above. (2 points) After conducting the study, the researchers obtained the results in the graph below. Based on these results, do you reject or fail to reject your hypothesis? Explain. (2 points)
