If many random samples of 64 students who took the second midterm examination in Math 10 are taken, what is the 95th percentile of the average time to completion for these samples?
\n" ); document.write( "---
\n" ); document.write( "Find the z-value with a left tail of 0.95
\n" ); document.write( "invNorm(0.95) = 1.645
\n" ); document.write( "-----
\n" ); document.write( "Find the corresponding exam score using x = zs+u
\n" ); document.write( "x = 1.645*s + u
\n" ); document.write( "---
\n" ); document.write( "Comment: You need to be given s and u.
\n" ); document.write( "-----------------
\n" ); document.write( "Explain what this number means.
\n" ); document.write( "95% of the sample means are less than 1.645s+u
