In a qualification test for the swimming world finals, the following data is recorded for a swimmer. In resting condition: heart rate (HR) of 60 beats / min, a stroke volume (VS) of 85 mL / min. During maximum effort in a test race on a slope: HR of 170 beats / min and a VS of 135 mL / beats. This swimmer weighs 68 kg and measures 178 cm.
a) Calculate cardiac output (CO)
b) Calculate the body surface area according to the Dubois-Dubois equation
c) Calculate the cardiac index for the swimmer
d) This athlete has been diagnosed with attention deficit hyperactivity disorder ADHD, and in her case the sympathetic nervous system is very active. Briefly explain how this influences the Starling effect and stroke volume.

Open the Corn Yield dataset. There you see data recorded from an experiment to test 4 organic pesticide methods (wasps, nematodes, pepper spray, and bacteria) to see if they eradicate corn weevils better than a standard chemical pesticide (control). For each method, effectiveness is determined by the average weight in grams of corn that is yielded from a randomly selected ear of corn. Use Minitab to do an Anderson-Darling test on the Yields to determine if the normality assumption for...

Energy markets are flashing a warning: The world is swimming in crude oil, and the glut won't drain away any time soon. Twin shocks -- the coronavirus pandemic and the breakdown of Russia's partnership with the Organization of the Petroleum Exporting Countries -- threaten to flood the market with cheap oil at a time when demand is falling. That has caused the relationship between oil prices at different dates, a closely watched barometer of the balance between supply and demand,...
