DID POWERADE “HELP YOU TO RETAIN FLUID”?

Powerade (the isotonic saline drink in the Diuresis lab) advertising claims that it “helps you to retain fluid.”

EXPLAIN, using the statistical analysis of the class data, whether Powerade had a significant effect (or not) on the water diuresis. Indicate whether the statistical analysis of the class data supports the claim that Powerade “helps you to retain fluid”. In your answer, you must refer to the statistical analysis (including the P value, if this is significant, and the direction of change). 

Explore the research literature and find evidence (a primary scientific paper), for the effects of an isotonic solution on human urine output, relative to water. EXPLAIN, citing this research (and add the Reference at the bottom of your answer), the expected actions of an isotonic solution on a water diuresis. How could you modify the experimental procedures and/or measurements for this BMS2031 ‘Diuresis’ lab so that the body fluid effects of an isotonic solution are shown?
