Phd tim-demonstrate inferences using two samples-see attached


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.  This assignment should strengthen your understanding of hypothesis testing.
