H1 =Levels are too different to have occurred purely by chance Statistical test: T test P < 0.0001 (extremely significant) Reject null hypothesis (Ho) and accept alternate hypothesis (H1) ie. 1 in 10 000 chance that these samples are both from the same overall group therefore we can say they are v ...

... It describes the variability of sample means that could occur just by chance and thereby serves as a frame of reference for generalizing from a single sample mean to a population mean. It allows us to determine whether, given the variability among all possible sample means, the one observed sample m ...
