STAT 100 Lecture Notes - Lecture 12: Null Hypothesis, Statistical Hypothesis Testing, Test Statistic
Document Summary
Set the two competing hypotheses: null and alternative. Calculate a test statistic assuming null hypothesis is true. From test statistic we calculate p-value, p-value is the probability our sample data would produce the test statistic or one more extreme, assuming null is true. Make a decision and write up a conclusion. Note: null hypothesis always includes an equal sign, whether it is just an equal sign, or greater/less than. Note: mo is same placeholder for a value. Ho : p = po ha : p po. Ho : p po ha : p > po. Ho : p po ha : p < po. Ho : m = mo ha : m mo. Ho : m = mo ha : m > mo. Ho : m = mo ha : m < mo. Four steps to conducting a hypothesis test ( is symbol for less than or equal to.
