Professor Greens multiple choice test had 50 questions with the distribution of correct answers shown below. At a -.50 can you reject the hypothesis that Prof. Greens exam answers came from a uniform population.?
\n" ); document.write( "a 8
\n" ); document.write( "b 8
\n" ); document.write( "c 9
\n" ); document.write( "d 11
\n" ); document.write( "e 14
\n" ); document.write( "total 50
\n" ); document.write( "--------------
\n" ); document.write( "Ho: The proportions are all equal
\n" ); document.write( "Ha: At least one of the proportions is different.
\n" ); document.write( "---------------------------------------------------
\n" ); document.write( "Run a Chi-Sq on the data with Expected value for a,b,c,d,e = 10
\n" ); document.write( "---------------------------------------------------
\n" ); document.write( "To generate the test statistic:
\n" ); document.write( "1. Find (observed - expected)^2/expected for a,b,c,d,e
\n" ); document.write( "2. Add those results
\n" ); document.write( "Test statistic = 2.6
\n" ); document.write( "------------------------
\n" ); document.write( "Critical value for 1-tail Chi-Sq with alpha=5% and df=10-1=9 is 16.919
\n" ); document.write( "------------------------
\n" ); document.write( "Since 2.6 < 16.919, Fail to reject Ho.
\n" ); document.write( "The proportions are equal; the distribution is statistically uniform.
\n" ); document.write( "-------------------------------
