The following hypotheses are given.
\n" ); document.write( "H0 : π ≤ 0.83
\n" ); document.write( "H1 : π > 0.83
\n" ); document.write( "A sample of 140 observations revealed that p-hat = 0.88.
\n" ); document.write( "At the 0.05 significance level, can the null hypothesis be rejected?
\n" ); document.write( "a. State the decision rule. (Round your answer to 2 decimal places.)
\n" ); document.write( "Reject H0 if z > invNorm(0.95 = 1.645?
\n" ); document.write( "----------
\n" ); document.write( "b. Compute the value of the test statistic. (Round your answer to 2 decimal places.)
\n" ); document.write( "z(0.88) = (0.88-0.83)/sqrt[0.83*0.17/140] = 1.5750
\n" ); document.write( "Value of the test statistic = 1.5750
\n" ); document.write( "---------------------
\n" ); document.write( "c.What is your decision regarding the null hypothesis?
\n" ); document.write( "(reject/no not reject) H0.
\n" ); document.write( "Fail to reject Ho.
\n" ); document.write( "--------------
