Class 10 - 2016-11-14

• Have to make a decision, limited amount of evidence, could be wrong
• Dueling hypotheses for hypothesis test,
  • h0 - null status quo
  • h1 - alternative hypothesis
• type I error: Null Hypothesis is incorrectly rejected (alpha)
• type II error: Alternative (research) Hypothesis is incorrectly rejected (beta)
• always set up the bell that its true, show your positive control is outside of normal distribution.
• left tail
• draw the line in the sand where on teh tail demarks the decision boundary ("alpha", level of significance)

• The equals sign ALWAYS goes in the NULL hypothesis
• The status quo is always in the center, the rejection is always in the tails.
