Question

my teacher WANTS ME TO DO THIS PROBLEM ON CALCULATOR. WHAT IS THE EASIEST WAY? OR IS THE WAY YOU SHOWED IS THE ONLY WAY. the problem used is for computing probabilities  of a sample proportion. I see how it is done by hand but missed class the day my teacher went over calculating by calculator. 

Explanation / Answer

To do this on a Ti 83 and Ti84 you go to stat -> test -> thenselect the test you need. For sample proportion go to 1-PropZTest. For P0 put thepopulation proportion if given, if not use the sample propotion.Then multiply the n by the sample proportion to get x:... Finallyplug in the n value and decide which test you are looking for. *Click draw if you are unsure, this allows you to visually see thepicture. *Click calculate for the value. I hope this works. If this does not please feel free to message meand I will try my best to help you out.
