A sample of 900 observations taken from a population produced a sample proportion of 0.32.
Make a 90% confidence interval for p. Round the answers to 3 decimal places.
-----------
standard error: 1.645*sqrt[0.32*0.68/900] = 0.026
-----------------------------------
90% CI: 0.32-0.026 < p < 0.32+0.026
90% CI: 0.294 < p < 0.346
