Homework Help: Statistics

Posted by Katie on Thursday, June 27, 2013 at 5:55pm.

Politicians are interested in knowing the opinions of their constituents on important issues. One administrative assistant to a senator claims that more than 63% of adult women favor stricter gun laws. A recent telephone survey of 1026 adult women by IBR Polls found that 65.9% of adult women favored stricter gun laws.

Create a 90% confidence interval for the true proportion of adult women who favored stricter gun laws. Find the upper and lower bound. Show your results as percents correct to tenths of a percent.
