Before said suspected illegal connection, a mercury difference of 350 mm was observed while a mercury difference of 200 mm was observed afterwards. Estimate the stolen volume of water per day.The National Institute of Diabetes and Digestive and Kidney Diseases reports that the average cost of bariatric (weight loss) surgery is about $22,500. You think this information is incorrect. You randomly select 30 bariatric surgery patients and find that the average cost for their surgeries is $21,545 with a standard deviation of $3015.
