STAT 110: Notes for Week of 10/25/16 Chapter 21 o This section will focus on interpreting data and inferential statistics (making inferences about a population based on data from a population sample). o The sample proportion probably is not equal to the parameter. Sample proportion: p = (# of successes/n) n = number...
