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 of subjects in the sample o The sample mean is never equal to the population mean. o Since the sample proportion is probably not equal to the parameter, we will take a confidence interval (sample proportion +/- the margin of error) to make a more confident statement about the data. o Sample distribution: the distributio
