We are learning how to compute confidence intervals for both a population mean and a population proportion. In this activity, each student will construct a 95% confidence interval for the population proportion of whole numbers that are odd.

1. What do you suspect is the true proportion of whole numbers that are odd? _________. Why do you suspect this?

2. If each of 20 people generated a random sample of whole numbers and constructed a 95% confidence interval for the proportion that are odd, how many intervals are expected to contain the true proportion? __________
