Homework Help: Statistics

Posted by Motu on Saturday, November 2, 2013 at 8:59am.

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.

The 90% confidence interval is: ( % , %)

Enter each number as a percent rounded to tenths of a percent.

I got 63.5 to 68.3. Is my answer correct?
