Create confidence interval-whom traffic congestion problem

Reference no: EM13112452

The table shows results of a survey in which separate samples of 400 adults each from the East, South, Midwest, and West were asked if traffic congestion is a serious problem in their community. Complete parts a & b.

Adults who say that traffic congestion is a serious problem:
East 34%
South 33%
Midwest 26%
West 56%

Construct a 95% confidence interval for the proportion of adults from the West who say traffic congestion is a serious problem.

The 95% confidence interval for the proportion of adults from the West who say traffic congestion is a serious problem is ( ), ( ). Round to three decimal places as needed.
