Scientists proposed the hypothesis: consumption of omega-3 fatty acid can reduce the size of cancerous tumors. the following hypothesis was tested. a sample of 500 rats with tumors was collected. within this sample size, 250 rats were feed with omega-3 (group 1) while the raining 250 rats were not (group 2). after one month of periodically feeding group 1 with omega-3 fatty acid, rat autospies were taken for both groups. the average changes of tumor size were measured and recorded. p value was .04. average change of tumor size group 1 -.124g group 2 -.012g. based on the results from the experiments, which of the following is the best conclusion? a. consumption of omega-3 fatty acid decreases the size of previous cancerous tumors with statistical significance. correctb. consumption of omega-3 fatty acid has no effect on decreasing the size of previous cancerous tumors. c. absence of omega-3 fatty acid in the diet directly decreases the size of previous cancerous tumors. d. absence of omega-3 fatty acid in the diet decreases the size of previous cancerous tumors with statistical significance. e. consumption of omega-3 fatty acid directly decreases the size of previous cancerous tumors.

A35-year-old woman comes to the ed complaining of chest pressure. she has had such episodes intermittently over the last 5 years, usually when sleeping, but over the last year she has had more frequent severe symptoms that are occasionally associated with severe migraine headaches. the pain is midsternal and is described as pressure that extends as a band around her chest. the ed physician is initially dubious that the pain is cardiac in origin, because the woman has no coronary disease risk factors. an ecg, however, shows 2mm st-segment elevation and inverted t waves in leads v1 through v5 and 1mm st-segment depression in leads ii, iii, and avf. before the cardiologist arrives in the ed, the patient's ecg has returned to normal. this repeat normal ecg is obtained after the administration of aspirin, nitroglycerin, morphine, and oxygen. which of the following is most likely for these findings? - diffuse intimal thickening with focal areas of atherosclerotic narrowing - intermittent thrombus formation and lysis in the left anterior descending artery - intermittent thrombus formation and lysis in the right coronary artery - plaque rupture and thrombus formation in the left anterior descending artery - transiently increased coronary vascular tone in the right coronary artery
