I'd like to help you all get started on the CT assignment. Let me walk you through that. I am also
very open to us working on the CT calculations together!
We'll set the confidence interval calculations up just like Example 3 from P. 334. First though, we
need to use Formula 71 on P. 333 to determine the margin of error. We know from previous
examples that a 95% confidence level corresponds to a critical value of z
α/2
= 1.96.
Now we need to find the values of phat and qhat. You can then subtract that phat from 1 for your
qhat.
Now plug the CV and phat and qhat into the Margin of Error formula. Finally, set up your CI using
phat and E values.
Hint: There is an orderly progression to these problems, and by following the order it keeps your
sanity intact (and it is easier for others to follow you!). I would strongly suggest laying out your
