Hmm. Get back to you soon. Got a class to teach.\r
\n" ); document.write( "\n" ); document.write( "Back now.
\n" ); document.write( "14.
\n" ); document.write( "a.) \"525%2F1230+%2B-+2.325sqrt%28%28%28525%2F1230%29%2A%28705%2F1230%29%29%2F1230%29\". This corresponds to the open interval (0.39404, 0.45962).
\n" ); document.write( "b.) No, it is not reasonable to conclude from the sample that the president is doing a good job. In fact we could say that the true proportion may be less than 50%. (As opposed to the null hypothesis that the true proportion is equal to or greater than 50%.)\r
\n" ); document.write( "\n" ); document.write( "15.
\n" ); document.write( "a.) $63/hr.
\n" ); document.write( "b.) Using the t-distribution with 22 degrees of freedom, the C.I. is \"63%2B-+%282.508%29%2A%286.1%2Fsqrt%2823%29%29\". This corresponds to the open interval (59.81, 66.19).
\n" ); document.write( "c.)We use the standard normal table again. We want \"1%3E=1.645%2A%286.1%2Fsqrt%28n%29%29\". This should give \"sqrt%28n%29%3E=10.0345\", or \"n%3E=100.69\". We can put n = 101.
