Conducts a search of the space of decision trees which can represent all possible discrete functions. . What is hypothesis testing?. A statistical hypothesis is an assumption about a population parameter. This assumption may or may not be true. . The best way to determine whether a statistical hypothesis is true would be to examine the entire population. Since that is often impractical, researchers typically examine a random sample from the population. . (1-Sample). STEP 1, Null and Alternate Hypotheses.
