** Week 4 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. **** Please answere the question in the attached documents.
***Week 5’s assignment is quite similar to that of Week 4. Instead on inferences, you can make regarding a single sample, you will make inferences regarding two samples. Once again, you will formulate a confidence interval to estimate the population means. You will consider two independent samples as well as two paired samples, for example, a sample that represents some characteristic before and after the introduction of some stimulus. You will also study two population proportions.
