1. Calculate confidence intervals at the 95% level using the Penn State football championship voting 80/20 split examples on Page 2 and use samples of 50, 500, 2000, and 5000 to see the point of diminishing returns for yourself.

2.Calculate confidence intervals around the P and Q percentages using the following sample data:

1. P = 75% , Q = 25% n= 678 @ 95% level of confidence
2. P = 75%, Q = 25% n= 35 @ 95% level of confidence
3. P = 52%, Q = 48% n= 678 @ 99% level of confidence
