Question 1: A test has a mean of 30 and a standard deviation of five.
\n" ); document.write( "Comment:: Convert all the scores to z-scores.
\n" ); document.write( "-----------
\n" ); document.write( "Jackie has scored in the 57th percentile.
\n" ); document.write( "z-score = invNorm(0.57) = 0.176
\n" ); document.write( "---------------------------------------
\n" ); document.write( "Ethan has a T score of 70.
\n" ); document.write( "Comment:: Are you sure? That would be 70 standard deviations above the mean.
\n" ); document.write( "---------------------
\n" ); document.write( "Lan has obtained a z score of –0.2.
\n" ); document.write( "------------
\n" ); document.write( "Salvatore has received a raw score of 27.
\n" ); document.write( "z(27) = (27-30)/5 = -3/5 = -0.6
\n" ); document.write( "----------------------------------
\n" ); document.write( "On the basis of the information provided, answer the following questions:
\n" ); document.write( "Who has scored the highest?
\n" ); document.write( "Excluding that \"T\"score, Jackie's score is highest.
\n" ); document.write( "---------
\n" ); document.write( "Who has scored the lowest?
\n" ); document.write( "Salvatore's is the lowest.
\n" ); document.write( "-------------------------------
