In a recent poll, 600 people were asked if they liked soccer, and 72% said they did. based on this, construct a 99% confidence interval for the true population proportion of people who like soccer.

as in the reading, in your calculations:
--use z = 1.645 for a 90% confidence interval
--use z = 2 for a 95% confidence interval
--use z = 2.576 for a 99% confidence interval.

give your answers as decimals, to 4 decimal places.
