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. Demonstrate the calculation process from the beginning to the end. ALSO, discuss the point of diminishing returns; specifically, what happens when the sample size changes? *(Page 2 80/20 split: Do you think Penn State will emerge as national champions this year? Yes 80% No 20%) 2. Calculate confidence intervals around the P and Q percentages using the following sample data: P = 75%, Q = 25% n = 678 @ 95% level of confidence P = 75%, Q = 25% n = 35 @ 95% level of confidence P = 52%, Q = 48% n = 678 @ 99% level of confidence
