This week’s assignment is focused on inferences you can make regarding a single sample, whether you have a “large” sample of more than 30 items or a “small” sample of 30 items or fewer.  You will formulate a confidence interval to estimate the population mean for both a large and small sample as well as for a large sample population proportion.  In addition, you will construct a hypothesis test for a population mean, again for both a large and small sample and a large sample population proportion.
