Examples of Negative Portrayals of One-Sided Significance
TESTS FOR A SINGLE BINOMIAL POPULATION. Pele, Before you can determine which test to use, you need to determine how you will measure things. For example, in hypothesis 1, how will you measure “cooperation”?, I was wondering given a one-sided (one-tailed) hypothesis with an alpha-level of .05, can we be talking about 95% confidence intervals? For example, can we construct.
