In a July 2012 Gallup poll based on a representative sample of 1014 adult Americans, 48% reported drinking at least one glass of soda pop on a typical day. Now suppose that we test the null hypothesis π = 0.50 vs. the alternative hypothesis π ≠ 0.50.
Use the One Proportion applet for a single proportion, repeatedly testing other possible values for π, to determine plausible values and construct a 99% confidence interval for π. Round your answers to three decimal places.
99% confidence interval = ( , )
