Phd tim-demonstrate inferences using a single sample-see attached

 

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. 

Download Data File 4 Attachment 4 and complete the questions and answers as presented.  Unless otherwise requested, submit all assignments with the problems/questions and answers in Word file format.
